Question

rewrite in simplest terms: $-4(-8w - 4x) - 7x - 10(-10x + 8w)$

Explanation:

Step1: Expand all parentheses

$(-4)(-8w) + (-4)(-4x) - 7x + (-10)(-10x) + (-10)(8w)$
$=32w + 16x - 7x + 100x - 80w$

Step2: Combine like w terms

$32w - 80w + 16x - 7x + 100x$
$=-48w + 16x - 7x + 100x$

Step3: Combine like x terms

$-48w + (16x - 7x + 100x)$
$=-48w + 109x$

Answer:

$-48w + 109x$
