Rewrite subtraction as an equivalent addition expression. 5(x – 4) + 3x – 9x + 7

iogann1982 [59]

Hello!

Explanation:

Distributive property: → a(b+c)=ab+ac

Expand the form equation.

$5(x-4)=5x-20$

$5x-20+3x-9x+7$

Then, simplify by equation or expand.

$5x-20+3x-9x+7=-x-13$

Final answer is: → $\boxed{=-x-13}$

*The answer must have a negative sign.*

Hope this helps!

Thank you :)
