What is the solution of equation 6z?

What is the solution of equation 6z?

Answer: Solution. 6z = -2 – 10 = -12 (Transposing 10 to R.H.S.)

What is an equation with a solution of?

An equation is a mathematical statement formed by placing an equal sign between two numerical or variable expressions, as in 3x+5=11 . A solution to an equation is a number that can be plugged in for the variable to make a true number statement. 3(2)+5=11 , which says 6+5=11 ; that’s true! So 2 is a solution.

How do you know if an equation has a solution?

A system of linear equations has one solution when the graphs intersect at a point. No solution. A system of linear equations has no solution when the graphs are parallel. Infinite solutions.

Which equation has no solution 4x 2 6?

Answer: Option A) |4x – 2| = – 6 has no solution. Since left hand side of function is in modulus, so it will always gives positive values but right hand side is – 6 , So, there are no values of x that make the equation true.

What is the answer of 3 N 5 )= 21?

Solve the eqation = 3(n-5)=21 We will get 36 when we add 21 and 15.

What is the answer of 3 by 5 2 by 7?

Answer: 3/5 + 2/7 can be represented as 31/35 as a fraction after addition. Let’s understand this in detail. Explanation: To solve the given problem, we need to add the given fractions using the common denominator property of fractions.

What must an equation have?

An equation is written as two expressions, connected by an equals sign (“=”). The expressions on the two sides of the equals sign are called the “left-hand side” and “right-hand side” of the equation.

What is an example of one solution?

9x – 8x = 37 + 35 + 9 = 80 which gives x = 80. Hence, the given linear equation has only one solution i.e. x = 80. From the above examples, we see that the variable x does not disappear after solving & we say that the linear equation will have one solution if it is satisfied by exactly one value of the variable.

What is the condition of no solution?

For no solution, Two lines have no solution, if these two lines are parallel to each other. The lines are parallel to each other means that the slopes of the lines are equal. Mathematical representation of the equation with no solution for the given set of general lines is: pu=qv≠rw.

What is an equation that has no solution?

No solution would mean that there is no answer to the equation. It is impossible for the equation to be true no matter what value we assign to the variable. Infinite solutions would mean that any value for the variable would make the equation true. Note that we have variables on both sides of the equation.

What is the ratio of 90 to 120?

Therefore, 90/120 simplified to lowest terms is 3/4.

Which is the correct solution to the equation 3?

SOLVING EQUATIONS USING ADDITION AND SUBTRACTION PROPERTIES. The solution of the original equation is the number -3; however, the answer is often displayed in the form of the equation x = -3. Since each equation obtained in the process is equivalent to the original equation, -3 is also a solution of 2x + 1 = x – 2.

Which is not a solution to the equation x = 5?

Example: x − 2 = 4 1 For x=5 we get “5−2=4” which is not true, so x=5 is not a solution. 2 For x=9 we get “9−2=4” which is not true, so x=9 is not a solution. 3 etc

Is it impossible for an equation to have a solution?

Notice – his version has no “x”. It is false as 3 will never equal 5. So, it is impossible for the equation to have a solution. He shows you a 2nd example that starts out with variables and then becomes 3=2. Any value you pick for “x” and insert into this equation will result in the 2 sides not being equal.

How do you determine the solution of an equation?

The value of the variable for which the equation is true (4 in this example) is called the solution of the equation. We can determine whether or not a given number is a solution of a given equation by substituting the number in place of the variable and determining the truth or falsity of the result.
