Y = 6x - 11
-2x - 3y = -7

Let's use substitution:

-2x - 3y = -7
-2x - 3(6x - 11) = -7
-2x - 18x + 33 = -7
-20x + 33 = -7
-20x = -40
x = 2

----

y = 6x - 11
y = 6(2) - 11
y = 12 - 11
y = 1

----

y = 6x - 11  =>  1 ? 6(2) - 11  =>  1 = 12 - 11  <--True
-2x - 3y = -7  =>  -2(2) - 3(1) ? -7  =>  -4 - 3 = -7  <--True

Answer:
x = 2
y = 1

Hope this helps!
