how do you solve this problem 38(35-5.5x)=16(5x-8)+70.8

Apr 25th, 2015

first multiply the number outside the parenthesis by whats inside

1330- 208x = 80x - 128 + 70.8

now move the x terms to one side and the whole numbers  to the other

subtract 1330 form both sides and - 80x from both sides

-208x -80x = -128 +70.8 - 1330

-288x= -1387.2 

now divide both sides by -288 to solve for x

x = 4.81666667
