Follow a systematic, consistent approach to solving algebra problems.

1. Multiply out using the distributive law.
2. Group like variables together on each side of the equation.
3. Add and/or subtract terms so that all the variables are on one side of the equation and all the numbers are on the other.
4. Multiply or divide to find the value of the unknown.

8(f+3) = 10f - 32 Multiply out
8f +24 = 10f - 32
-10f = -10f add -10f to both sides
-2f + 24 = -32
-24 = -24 add -24 to both sides
-2f = -56
f = 28 divide both sides by -2

Checking the answer in the original problem

8(28 + 3) = 10(28) - 32
8(31) = 248 and 280-32 = 248

Okay... this got me a little confused!

8(f+3) = 10f - 32
8f+24 = 10f - 32 < Use the distributive property
8f + 56 = 10f < Add 32 to each side
56=2f < Subtract 8f from each side
28 = f < Divide 56 by 2

8 (f + 3) = 10f - 32

You have to time (f + 3) by 8.

= 8f + 24 = 10f - 32

Now we have to get all the F variables on one side of the '='

= 8f - 10f + 24 = 10f - 10f - 32

I just got rid of the 10f on the right side by minusing, so now I have to minus it on the left side, so the equation is now:

-2f + 24 = -32

Lets get the f variable on it's own.

-2f + 24 - 24 = -32 - 24
= -2f = -56

We have to get f on it's own so we divide -2f by -2.
which means we have to divide the right side (-56) by -2.
(/ means divide)

-2f / -2 = -56 / -2

(=) f = 28

-56 / -2 = positive 28 because a negative and a negative = a positive ( - - = +)

same goes for -2f / -2.

So write out your answer like:

8 (f + 3) = 10f - 32
= 8f + 24 = 10f - 32
= 8f - 10f + 24 = 10f - 10f - 32
= -2f + 24 = -32
= -2f + 24 - 24 = -32 - 24
= -2f = -56

= -2f / -2 = -56 / -2

= f = 28

Just distribute and solve

8(f+3) = 10f-32
8f+24 = 10f-32
56 = 2f
28 = f

first distribute the 8 so you get 8f+24=10f-32 next you get all the variables to one side so you get 24=2f-32 and then add the 32 and get 56=2f then divide by 2 on and get f=28

here are the steps[[:
first you need to deduce 8(f+3)
so use the distributive property so it becomes 8f+24
then try to get f in one side and the other # to the other 8f+24=10f-32
subtract 8f
24=2f-32
then add 32 so you can get 2f by its self
56=2f
now divide 2 so you have f alone.
28=f
and that's the answer. if you didn't understand than you can ask me again or post it up again[[:
try step by step it helps

8f+24 = 10f -32
10f -8f=24+32 so 2f =56 and f =28

8f + 24 = 10f-32
8f + 24 - 24 = 10f -32 -24
8f = 10f- 56
8f - 10f = 10f - 56 - 10f
-2f=-56
-2f/-2=-56
f=28

Hope this helps! (if you wanna pass math you should probably learn how to do it yourself)
