Question

2/3x-1/x

Answer 1

You need a common denominator. What would it be?

Answer 2

9 right?

Answer 3

No, what is similar in the denominators... 3x... x ?

Answer 4

x divides into 3x 3 times

Answer 5

The first fraction lacks an "X" and the 2nd fraction lacks a "3X"

Answer 6

on the dominator.

Answer 7

So your Common Denominator would be (3x)(x)

Answer 8

Oh alright gotcha

Answer 9

You would times 2 by "x" and 3x by "x"... since you want to make the 1st equation have the same denominator.

Answer 10

so it would be 2x/(3x)(x) - (3x)/(3x)(x)

Answer 11

2x-3x = -1x

Answer 12

the answer is -1x/(3x)(x)

Answer 13

so basically u would multiply the right side by the denominator of the left side and multiply the left side by the denominator of the right side?

Answer 14

kind of

Answer 15

Yes, whatever the other doesn't have on the (bottom) denominator.. you have to TIMES it by the Numerator and the Denominator.. Whatever you do to the denominator you have to do to the numerator.

Answer 16

seems simple thanks bro u explained very well

Answer 17

Answer 18

and u know how 3x^2 doesnt go into 2x do u just write it as 2x-3x cause 3x doesnt go into 2x?
