Equations
o We find the M.C.M of 5,4,2,4 = 20, so we multiply everything by 20 so it allows us to created and easier expression.
o We put all the variables on one side, and all constants on the other side.
o In order to find x we divide 30 by 2.
¾ x – ¾ = ½ x + ¾
60/5 x – 60/4 = 20/2 x + 60/4
12x – 15 = 10x + 15
12x – 10x = 15 + 15
2x = 30
x = 30/2
x =15
