Alright, so this one is just like the last– we need to get x all by itself, to find its value.  First, add 10 to each side of the equation (note: we add because 10's sign is -. If 10's sign was +, we would subtract.) 3x - 10 = 20 +10          +10 3x = 30 Then, divide by 3 on each side.  3x = 30 /3     /3 x = 10 Hope that helps!!

3*10=30-10=20 that's the easy way to do it
