Question

how do i simplify this equation?

Answer 1

Where's the equation?

Answer 2

-2a+1/3b-7a-b

Answer 3

Collect like terms first

Answer 4

oh ok thanks

Answer 5

what do i do with the 1/3b and - b

Answer 6

What did you end up with?

Answer 7

-9a and then idk what to do

Answer 8

Well you can't do that cause the a terms are in diff places. One is in the numerator and the other is in the denominator

Answer 9

so how do i work it?

Answer 10

(-2a+1)/(3b-7a-b) = (-2a+1)/(2b-7a)

Answer 11

oohhh

Answer 12

The have to be in the same place to collect the like terms

Answer 13

i see thanks

Answer 14

No problem :3

Answer 15

i still dont get it its supposed to be one third b not 3b

Answer 16

If its one third b then this is how your expression should look like:\[2a + (\frac{1}{3}b) -7a-b\]

Answer 17

Ohhhh that's what he meant ^

Answer 18

You have to combine like terms and you have two terms here which are variables a and b. So you combine terms with a and you combine terms with b. The way you combine these variables which are like terms is by adding the coefficients which are the numbers in front of the variables

Answer 19

Yeah I think so

Answer 20

\[2a -7a = -5a\]

Answer 21

It's just simple math where you group the ones with the same variables together.

Answer 22

\[\frac{1}{3} b - \frac{3}{3}b = -\frac{2}{3}b \]

Answer 23

So the final answer is : \[-5a - \frac{2}{3}b \]

Answer 24

its -2a

Answer 25

thanks you helped alot !

Answer 26

oh okay -2a - 7a = - 9a and you're welcome!
