-14 + 5u = -9u add 9u to both sides
-14 + 14u = 0 add 14 to both sides
14u=14 divide both sides by 14
1: Simplify the problem by moving all similar figures together (normal numbers like 1 or -1 go to their side, numbers with letters attached go to a different side.)
2: Divide to get rid of the number attached to the letter. REMEMBER! Always do the same thing to both sides.
3: The answer with be _= number, or number=_ (i.e. 10=a or b=-6)
