How to solve -2(-4f+5)=-7+2f-9

Damm [24]

Answer:

$f=\frac{3}{5}$

Step-by-step explanation:

$-2(4f+5)=-7+2f-9$

First, use PEMDAS to distribute the -2 to the parenthesis.

$-8f -10 = -7+2f -9$

Combine like terms on the right side.

$-8f - 10 = -16+2f$

Now, you may either subtract the f's or the constants. I'll subtract the constants first, meaning I will add 10 to both sides.

$-8f = -6 + 2f$

Now subtract the 2f from both sides.

$-10f = -6$

Divide both sides by 10.

$f = \frac{-6}{-10}$

Simplify.

$f = \frac{3}{5}$
