Answer:

<h2>x=2 (answer should have a positive sign.)</h2>

Step-by-step explanation:

To solve this problem, you have to isolate the x from one side of the equation.

First, switch sides.

8=2x+4

2x+4=8

Subtract by 4 from both sides.

2x+4-4=8-4

Solve.

8-4=4

2x=4

Then, divide by 2 from both sides.

2x/2=4/2

Solve.

4/2=2

x=2

The solution is 2.
