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.
