Jason solved the following equation to find the value for

-8.5x - 3.5x = - 78

x = 6.5

Describe how Jason can check his answer.

-8.5 (6.5) - 3.5 (6.5) = - 7.8

-7.8 = - 7.8

Answer:-55.25 - 22.75 = - 78

Step-by-step explanation:

To check the answer, we plug the value of x into the equation;

Since x is given as 6.5, equation will be written as:

-8.5 (6.5) - 3.5 (6.5) = - 78

(-8.5 x 6.5) - (3.5 x 6.5) = - 78

-55.25 - 22.75 = - 78
