Question

Which is the value of x that makes the given equation true? Circle the answer choice that makes the most sense, below. Show all the steps to prove your answer is correct for full credit

x-3x=2(4+x)

A. x = -2
B. x = 0
C. x = 2

Answer 1

For this x would equal -2. You have to simplify both sides down to get the answer.

My work:

• First, add like terms: -2x=8+2x
• Next, do inverse operations: -2(-2)=8+2(-2)
• Now, you should be left with this: -4x=8
• Then, divide both sides by -4: -4x(/-4)=8(/-4)
• You should be left with x=-2 (This is your answer! :D)

I hope that this helps you out, bud! :3
