Answer:

x = 1

y = 7

Step-by-step explanation:

Two equations, two unknowns. We know that y = 7x so we can substitute that into the first equation to get:

[tex]-5+2\left(7x\right)=9[/tex]

[tex]-5+14x=9[/tex]

[tex]14x=14[/tex]

This gives us x = 1.

Now plug this bag into either equation to find y, I will use the second since it's easier:

y = 7(1) = 7
