Question

How do I do no.3????? Please answer asap!!!!!

Answer 1

3x - 6 = x

Subtract x from both sides
3x - x - 6 = x - x

2x - 6 = 0

Add 6 to both sides
2x- 6 + 6 = 0 + 6

2x = 6

divide both sides by 2
2x/2 = 6/2

x = 3



Hope it helps!

Answer 2

minus x from both sides
3x-6-x=x-x
2x-6 =0
plus 6 on both sides
2x-6+6=0+6
2x = 6
divide both sides by 2
2x/2 =6/2
x = 3
