1. Which is the solution to the following equation

2x + 4 = 8
x = 8 <------my answer

x = 6

x = 2

x = 1


can somene check my answers

2x +4 = 8
___ -4 __-4
(subtract 4 from both sides to get X by it self)

2x = 4

Divide by 2 on both sides

X=2 is the correct answer.

if you plug in 8, the answers won't match:
2(8)+4=8
16+4=8
20 does not equal 8...

therefore the correct answer is x=2.
2(2)+4=8
4+4=8
8=8
