Question

rewrite in simplest terms: 10(-7x + y) + 10y - 7(-2y + 8x)

Explanation:

Step1: Apply distributive property

$10(-7x + y) = -70x + 10y$
$-7(-2y + 8x) = 14y - 56x$
The expression becomes: $-70x + 10y + 10y + 14y - 56x$

Step2: Combine like x-terms

$-70x - 56x = -126x$

Step3: Combine like y-terms

$10y + 10y + 14y = 34y$

Step4: Combine simplified terms

$-126x + 34y$

Answer:

$-126x + 34y$
