Question

5 Solve for x. 8 = 2x + 4​

Answer 1

8 = 2x + 4

collect like terms

8 - 4 = 2x

4 = 2x

divide both sides by 2

4/2 = 2x/2

X = 2

Answer 2

x=2 (answer should have a positive sign.)

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.
