Answer:
(9, 0)
Step-by-step explanation:
We have to solve the system of equations given:
x + 2y = 9
x + 7y = 9
Firstly, lets solve for x in the 1st equation:
x = 9 - 2y
Now substitute this into 2nd equation to solve for y:
x + 7y = 9
(9 - 2y) + 7y = 9
9 -2y + 7y = 9
5y = 0
y = 0
Now replacing y = 0 into first equation, we can solve for x:
x + 2y = 9
x + 2(0) = 9
x + 0 = 9
x = 9
So, the solution is x = 9, y = 0
or
<u>(9, 0)</u>
