Solve the second equation. 2x - y = 8 First, solve for (-y). --y =

kicyunya [14]

Answer:

$-y=-2x+8\\y=2x-8$

Step-by-step explanation:

To solve, first subtract 2x from both sides.

$2x-y=8\\-y=-2x+8$

You appear to want the solution for -y, so I've included it. Given that you also want the solution for y, divide both sides by -1.

$-y=-2x+8\\y=2x-8$
