I can't figure this problem out.
3x-2y if x=-2 and y=-6

3x - 2y

In place of the x put (-2),
and in place of the y put (-6).

3(-2) - 2(-6)

Multiply the 3 by the (-2) and get -6, so put
(-6) in place of the 3(-2)

(-6) - 2(-6)

Multiply the 2 by the (-6) and get -12, so put
(-12) in place of the 2(-6)

(-6) - (-12)

Now change the subtraction - (-12) to an
addition " + 12 ".

(-6) + 12

Combine those and get 6

That's the answer, 6.
