Solve the following system of equations.
- 9x - 5y=1
- 6x - 7y=8

Let's solve by eliminating
x
. Since 18 is the lowest common multiple , let's multiply the first equation by 3 and the second by -2.

Add the two equations.

Divide by -11 to isolate
y

y= -2

Substitute
y
=
−
2
into either of the 2 equations, I'll just use the second one.
x = -1
