(2,-2)

Step-by-step explanation:

3x−6y=18

Step 1: Add -3x to both sides.

3x−6y+−3x=18+−3x

−6y=−3x+18

Step 2: Divide both sides by -6.

=

y = 1/2x -3

2x+6y=−8

Step 1: Add -2x to both sides.

2x+6y+−2x=−8+−2x

6y=−2x−8

Step 2: Divide both sides by 6.

6y/6 = −2x−8/6

y=−13x+−4/3

y= −13x+ −4/3
