remmeber, you can do anything to an equation as long as you do it to both sides


3x-3=x-4
get placeholder to one side
minus x from both sides
3x-x-3=x-x-4
2x-3=0-4
2x-3=-4
add 3 to both sides
2x+3-3=3-4
2x+0=-1
2x=-1
divide both sides by 2
x=-1/2

3x-3=x-4

Add 4 to both sides

3x+1=x

Subtract 3x from both sides

1=-2x

Divide both sides by -2

x=-1/2
