3. C.(10,-1)

4. (-9,2)

Please mark me BrainIIest

Explanation:

1.I will solve your system by substitution.

−x+2y=6;6y=x+18

Step: Solve−x+2y=6for x:

−x+2y+−2y=6+−2y(Add -2y to both sides)

−x=−2y+6


(-x)/(-1) =(-2y)/(-1) Divide by -1

x=2y−6\

Well I did this problem differently I substitute

Step: Substitute2y−6for x in6y=x+18:

6y=x+18

6y=2y6+18

6y=2y+12

6y+−2y=2y+12+−2y

4y=12


(4y)/(4) =(12)/(4)

y=3

Step: Substitute3 for y in x=2y−6:

x=2y−6

x=(2)(3)−6

x=0

Your final answer will be x=0 and y=3
