The object of any equation with a variable (whether it is on one side or both) is to isolate the variable. We do this by moving all of the x's to one side of the equation and everything else to the other side.

For example:

3x - 5 = 2x + 1

-2x -2x

x - 5 = 1

+5 +5

x = 6

Now, there are 3 different types of solutions:

1) x = ____ there is one solution

2) 0 = 0 or some other TRUE statement there are infinite solutions because every value for x is a solution

3) 0 = 1 or some other FALSE statement there are no solutions because no value for x will provide a solution
