To simplify the expression 7x - 4y - 8 - 3x - 8y + 12, we can combine like terms.
First, let's combine the x terms and the y terms separately:
(7x - 3x) + (-4y - 8y) = 4x - 12y
Next, let's combine the constant terms:
(-8 + 12) = 4
So, the simplified expression is 4x - 12y + 4.
simplify
7x-4y-8-3x-8y+12
