From my period 2 Algebra class

David Chen	First, find what x equals. 5x + 18 = 20 (subtract 18) 5x = 2 (divide by 5) x = 2/5 Now, insert it into the other equation 2(2/5) + 3 4/5 + 3 3 4/5 or 3.8
praneeth	3.8
Guest	3.8. subtract 18 from each side now divide each side by 5 so x=.4 2(.4)+ 3= 3.8
Guest	3.8 idiot... get a life.
