so, if x is the number, what is
the sum of the number and three?
That's the first step. Then keep going. If you get stuck, come back with what you got so far.

4 ( x + 3 ) = 5 x - 2
4 * x + 4 * 3 = 5 x - 2
4 x + 12 = 5 x - 2 Subtract 4 x to both sides
4 x + 12 - 4 x = 5 x - 4 x - 2
12 = x - 2 Add 2 to both sides
12 + 2 = x - 2 + 2
14 = x
x = 14
4 * x + 4 * 3 = 5 x - 2
4 x + 12 = 5 x - 2 Subtract 4 x to both sides
4 x + 12 - 4 x = 5 x - 4 x - 2
12 = x - 2 Add 2 to both sides
12 + 2 = x - 2 + 2
14 = x
x = 14
