Answer:
x=16, y=39
Step-by-step explanation:
to solve y=2x+7
Substitute 2x+7 for y in y=3x−9
y=3x−9
( solve this like a normal problem)
2x+7=3x−9 (Add -3x to both sides)
-x+7=-9 (Add -7 to both sides)
-x=-16 (Divide both sides by -1)
x=16
Now that you found x you can substitute this in the other problem.
y=3(16)-9
y=39
Hopefully this helped!
