-14 + 5u = -9u     add 9u to both sides

-14 + 14u = 0      add 14 to both sides

14u=14               divide both sides by 14

u=1

-14+5u=-9u

 

-14+5u=-9u

      -5u   -5u

 

-14=-14u

-14/-14=-14u/-14

 

u=1

 

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)
