Question

Jenny is solving the linear equation 12 + 3x - 5 = 8x. What are the last two final steps?

a. 7 + 3x + 8
b. 7 + 3x - 8
c. 7 - 3x + 8
d. 7 - 3x - 8

Answer 1

To solve the linear equation 12 + 3x - 5 = 8x, combine like terms and then divide both sides by 5 to solve for x.

Step-by-step explanation:

To solve the linear equation 12 + 3x - 5 = 8x, we need to isolate the variable x on one side of the equation. Here are the step-by-step instructions:

1. Combine like terms: 12 - 5 = 8x - 3x -> 7 = 5x
2. Divide both sides by 5 to solve for x: 7/5 = x

So, the final answer is x = 7/5. In terms of the answer choices given, the last two final steps are:

d. 7 - 3x - 8
