Answer 1

its 3 over 4 not divided

Answer 2

\[\frac{3}{4}x-6=9\]
what happens if you add 6 to both sides?

Answer 3

ohhhh you get 15 and the other -6 cancles out

Answer 4

good job and you're left with
\[\frac{3}{4}x=15\]

Answer 5

now you want to get rid of the 3/4
what can you multiply by to get rid of it

Answer 6

right so you divide next? idk im confused

Answer 7

the 4?

Answer 9

you get 60.

Answer 13

ohhh sorry then your left with 3x?

Answer 14

exactly
now you have 3x=60
you want to get rid of the 3

x=20! :)

Answer 16

yay, you actually picked up on this quite quickly

ok just remember, if you ever do anything (add subtract multiply divide) on one side, you must do it on the other side otherwise it wouldnt be a balanced equation anymore

Answer 17

okay can you help me with two more?

Answer 18

sure

Answer 19

Thanks! :)
okay ummm -2/3y+12=-8 again -2 over 3

Answer 20

\[-\frac{2}{3}y+12 = -8\]
ok what do you think you should do first?

Answer 21

ummm subtract the 12 on both sides?

Answer 22

good and you will get
\[-\frac{2}{3}y = -20\]

ok what next?

Answer 23

umm multiply the 3?

Answer 24

it doesnt matter if you multiply by 3 or divide by 2 first
but yes
if you multiply by 3, then what will you get?

Answer 25

Wait its a negative 3?

Answer 26

if its not then the answer will be negative 60?

Answer 27

sorry if you're still here
multiply by -3 and you get
2y=60
then y=30
