This cannot be simplified further, but it can be converted to a mixed number (as opposed to an improper fraction).  

y=−9/2x+10

step-by-step explanation:

let's solve for y.

0−9x−2y=−20

step 1: add 9x to both sides.

−9x−2y+9x=−20+9x

−2y=9x−20

step 2: divide both sides by -2.

−2y

−2

=

9x−20

answer: 21$

step-by-step explanation:

$42 / $14 = 3   (ratio 3: 1)
