Combine like terms to simplify the expression:
7x + 3y – 2 + 6x – 1 – y2
a.–2y3 + 13x – 3
b.–y2 + 3y + 13x – 3
c.–y2 + 3y + 42x2 –3
d.–3y3 + 13x2 – 3

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
