**Steve**, Thursday, August 23, 2012 at 4:30amgetting rid of decimals and fractions is usually a good first step. In this case, we get

7y + 90 = 10y + 150

-3y = 60

y = -20

it could have been done without that. the procedure is to collect all the y's on one side, and the numbers on the other

.7y - y = 15 - 9

-.3y = 6

y = 6/-.3

y = -20
