Answer: D. (7, 0)
Step-by-step explanation:
[tex]4x+9y=28\\-4x-y=-28[/tex]
The xs can already cancel since 4x is positive for the first equation, but negative on the second.
Add the equations together
8y=0
Divide both sides by 8
y=0
Plug y into one of the equations
4x + 9(0)=28
Distribute 0
4x=28
Divide both sides by 4
x= 7
So your answer is (7, 0)
