C = 8.5x + 6y

8.5x + 6y = C

8.5x = C - 6y

x = (C - 6y)/8.5

First we move 6y to the other side. To do this, you subtract 6y on both sides

C - 6y = 8.5x + 6y - 6y

C - 6y = 8.5x

No divide both sides by 8.5 to isolate x

\frac{C-6y}{8.5} =  \frac{8.5}{8.5} x =\frac{C-6y}{8.5} =x

Jake walks a mile to work. If Jake has already walked two-fifths of a mile, how many more feet must he walk to get to work?
Alexxx [7]
1 mile is equal to 5280 feet.

5/5 - 2/5 = 3/5 of a mile left to walk

3/5m * 5280 ft/1m = (3m*5280ft)/(5*1m) = 15840ft/5 = 3158 feet left to walk to get to work. 

Or
5280 feet / 5 = 1056 ft * 2 = 2112 ft walked to get to work
5280 - 2112 = 3168 feet left to walk to get to work.
