Don't let fractions frighten you. Just follow the same steps you would with any other number.

3/5(x + 2) = x - 4 You said to distribute. OK
3/5(x) + 3/5(2) = x - 4 Now simplify --- that is, work out as much as you can.
3/5(x) + 6/5 = x - 4 Now you have a variable on both sides of the equation. Subtract 3/5(x) from both sides.

6/5 = 2/5(x) - 4 Since 1 - 3/5 = 2/5, x - 3/5(x) = 2/5(x). Add 4 to both sides. Remember 4 = 20/5.

26/5 = 2/5(x) Almost finished ... Since you want one whole x and not 2/5 x, divide each side by 2/5.
Remember that dividing by 2/5 is the same as multiplying by 5/2. 26/5 times 5/2 equals 130/10 or 13.
13 = x

It's always a good idea to check your answer by plugging it into the original equation. I could be wrong. Check my answer. Good Luck with those fractions!
