# Homework help-Algebra problems?!

**Question:**Homework help-Algebra problems?

&

x/6+4=15

They may seem really easy to most people but i'm TERRIBLE at math :/

**Answers:**

question one: -1=b/4-7

you must simplify the denominator that is 4-7 which is 3, then you will get -1=b/3, then cross multiply that is 3*-1 you will get -3 and therefore your answer is -3.

question two: x/6+4=15

you do the same, simplify the denominator then find your answer, 6+4=10, then cross multiply 10*15=150 therefore x=150.

hope i helped you

I'm not sure which problem you have here b/c you forgot to use parenthesis

It could be:

-1 = (b/4) - 7

or

-1 = b/(4-7)

The second one has the same issue without the parenthesis

It could be:

(x/6) + 4 = 15

or

x/(6+4) = 15

If you put the parenthesis in we can answer them for you. I'll check back in later.

EDIT* I'll solve these equations the two different ways and you can use which one it was meant to be.

-1 = (b/4) -7; add 7 to each side

-1 + 7 = (b/4) - 7 + 7; simplify

6 = b/4; times both sides by 4

6 * 4 = (b/4)*4; simplify

24 = b <------------Answer

-1 = b/(4-7); subtract first

-1 = (b/-3); times both sides by -3

-1*(-3) = (b/-3)*-3; simplify

3 = b; switch it around

b = 3 <-----------Answer

(x/6) + 4 = 15; subtract 4 from both sides

(x/6) + 4 - 4 = 15 - 4; simplify

(x/6) = 11; times both sides by 6

(x/6)*6 = 11 * 6; simplify & solve

x = 66 <-----------Answer

x/(6 + 4) = 15; add

x/10 = 15; times both sides by 10

(x/10)*10 = 15*10; simplify & solve

x = 150 <---------Answer
