Question

How do I solve 3x-4=x+2? Please explain step by step

Answer 1

Okay, so we want to have the x's on one side. Subtract x.

$3x-4 = x +2$

$2x -4 = 2$

Now add 4 to both sides

$2x = 6$

Dive by two, to get x by itself.

$2x/2 = 6/2$

$x=3$

Answer 2

3x-4=x+2
Add 4 to both sides
3x=x+6
Then minus x from both sides
2x=6
Divide both sides by 2
x=3
