$-2x - 5y + 1$

Step 1) Expand the terms in parenthesis remember to use the correct sign across the entire term in the parenthesis:

$2x - 2y + 1 - 3y - 4x$

Step 2) Group like terms and simplify:

$(2x - 4x) - (2y + 3y) + 1$

$(2-4)x - (2+3)y + 1$

$-2x - 5y + 1$

How do you find the sum or difference of (2x-2y+1)-(3y+4x)(2x-2y+1)-(3y+4x)?
