Question

Nathan solved an equation 4(x – 1) = −1(6x – 36) for x. His answers is x = 2. Is he 2

correct? If so, explain the steps he used to solve the equation. If he is not correct, explain what he should have done to solve the problem.

Answer 1

He is not correct.

Explanation:

he should have done

4(x-1) = -1(6x-36)

=> 4x-4 = -6x+36

=> 4x-4+4 = -6x +36+4

=> 4x+6x = -6x+6x+40

=> 10x = 40

=> (10x)/10 = 40/10

=> x = 4.
