Answer 1

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

(9, 0)
