3 = 2x + 13
Subtract 13 from both sides
-10 = 2x
Divide both sides by 2
-5 = x

What you need to do is get the "x" factor on one side of equl sign. To do this, subtract 2x from both sides: {3-2x = 2x-2x+13}. Simpilfy to: {3-2x = 13}. Then, subtract the 3: {-2x=10}. Divide both sides by -2 to get {x=-5}.
