Eq. 2:
Start by putting the equations into standard form:
Eq. 1:

Eq. 2:
Let's start by eliminating the y variable. We need a constant to multiply the first equation and another constant to multiply the second equation so that the coefficients on the y variables become additive inverses. 7 * -9 = -63 and 9 * 7 = 63. That should work.
Eq. 3:

Eq. 4:
Now add the x terms together, the y terms together, and the constants together to create another equation that has a zero coefficient on y.
Eq. 5:
Go back to the original set of equations:
Eq. 1:

Eq. 2:
But this time, just multiply equation 2 by 2:
Eq. 6:

Eq. 7:
Add the equations to eliminate x
