Question

Can somebody help me with this? I don't want to put it through the calculator and learn it from there. I want someone to teach it to me :( (it's in the replies).

Answer 1

What do you think you do first? (Hint: Something with x)

Answer 2

Add -1/6x to 1/2x?

Answer 3

@StarfireAndRobin remember how you have to make the denominators equal

Answer 4

So 1/2 times 3/3?

Answer 5

that would get you 3/6

Answer 6

Oh, right. Nevermind that.

Answer 7

Ummm...

Answer 8

what is their least common denominator

Answer 9

12?

Answer 10

what is 6 x 7

Answer 11

Another thing you could do similar to that is to eliminate the fractions, so you would multiple everything by the common denominator/1 to get whole numbers. My teacher taught me that, and I find it pretty easy.

Answer 12

@asc.bchs, could you explain that better? And @jackthegreatest, 42

Answer 13

Please keep going @jackthegreatest

Answer 14

yep

Answer 15

\[\frac{ 2x }{ 7 } + \frac{ x}{ 2 } = -\frac{ 40 }{ 7 } - \frac{ x }{ 6 }\]

Answer 16

The LCM of 7, 2, and 6 is 42, so multiply everything by 42. So 2/7(42/1) is 84/7, or 12. If you repeat that with all the fractions, then you are working with whole numbers instead. Note that you MUST do this to both sides

Answer 17

That's what I meant^
