Question

I need help on last question.
Solve 2(x + 1) + 4 = 8.

1

6.5

4

3

Answer 1

2(x + 1) + 4 = 8 --- subtract 4 from both sides
2(x + 1) = 4 --- divide both sides by 2
x + 1 = 2 -- subtract 1 from both sides
x = 1

check..
2(x + 1) + 4 = 8
2(1 + 1) + 4 = 8
2(2) + 4 = 8
4 + 4 = 8
8 = 8 (correct)

So x = 1
