Jackson solved the problem 3x-8=2(2x-7) using the following steps:

STEP 1: Use Distributive Property to get 3x-8=4x-14
STEP 2: Use Addition Property of Equality to get 3x = 4x-14+8
STEP 3: Combine Like Terms to get 3x = 4x-6
STEP 4: Use Subtraction Property of Equality to get 3x-4x= -6
STEP 5: Combine Like Terms to get (-x)=-6
What is the last step?

A. Use Property of Equality to get x= (-6)
B. Divide both sides by -1 to get x=6
C. Divide both sides by -1 to get x= (-6)
D. Use Multiplication Property of Equality to get x=6

1 answer

To solve for \( x \) in the equation \( (-x) = -6 \), you need to divide both sides by -1. This will give you \( x = 6 \).

Thus, the correct option for the last step is:

B. Divide both sides by -1 to get x=6.
