# Thread: not very good at math

1. ## not very good at math

I know that I havent done my share of input, I appologize. I am not looking for the answers here but would like examples on how to do things (the steps)

I have a text book but it doesn't explain it very well. If you care not to answer, I understand. I will input if I know how to do something, I just dont want to give the wrong information to someone. I hope that you understand

I am looking for an example and steps on how to solve Equations

Thanks

2. What kind of equations?

3. x+3/8==5/12 just as an example

thanks

4. OK then, if you mean (x+3)/8 then this is what you do:

1: multiply each side by 8 over 1:
x+ 3 = 40/12
2: Subtract three from each side:
x = 40/12 - 3
Or in other words x = 6/12, which simplifies to 1/2

Basically the point is to get rid of denometors, then use reverse order of operations to isolate the variable on one side of the equal sign.

5. Just in case you meant:

x + (3/8) = 5/12

here is how to do it:

The main goal in all equations of this type is to move the variable(s) to one side of the equation and the rest to the other side.

In this case we will subtract (3/8) from both sides of the equation.

x + (3/8) - (3/8) = (5/12) - (3/8)

You are left with:

x = (5/12) - (3/8)

just simplify the right hand side to get the final answer

x = (10/24) - (9/24) ; 24 was the least common denominator for 12 and 8
