7x-4y-8-3x-8y+12

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.

To simplify the expression 7x - 4y - 8 - 3x - 8y + 12, you can combine like terms.

First, let's combine the terms with the variable x:
7x - 3x = 4x

Next, let's combine the terms with the variable y:
-4y - 8y = -12y

Now, let's combine the constant terms (numbers without variables):
-8 + 12 = 4

Putting it all together, the simplified expression is:
4x - 12y + 4
