X+2=3x+8

geometry

solve for x

X + 2 = 3x + 8

(Subtract 8 over)

x - 6 = 3x

(Commutative property, x on the left is easier to understand usually)

3x = x - 6

(Subtract x over)

2x = 6

(Divide both sides by 2)

x = 3

X+2=3x+8

Subtract 3x from both sides

x+2 - 3x = 3x + 8 - 3x - 2x + 2 = 8

Subtract 2 from both sides

-2x+2-2=8-2

-2x=6

Then divide both sides by - 2

You get x = - 3
