Answer 1

The answer is D, x = 3.

To find the answer to this, we need to solve for x.

4(x - 1) = 2(x + 1)

The first step is to either use the distributive property and get rid of the parenthesis or to divide each side by two. This shows division by two.

2(x - 1) = x + 1

Now we can get rid of the parenthesis

2x - 2 = x + 1

We want to get the numbers on one side and the variables on another

2x - x = 1 + 2

x = 3

Answer 2

Okay, So first you need to use multiply 4 by (x-1), which is 4x-4. Then you multiply 2 by (x+1), which is 2x+2. At this point you have 4x-4=2x+2. Now you combine the sides so one has the x variable and the other has a solo number. Subtract 2x from both sides and add four to both sides. Now you have 2x=6. Divide both sides by two to get x=3.

The answer is D. X=3
