Question

we

Answer 1

I had the same problem.

cross multiply
-10/ 2/3 = y/12

-10 * 12
2/3 * y

then do it like a regular equation

Answer 2

2/3y=-120

divide

y=-20

Answer 3

got it? or should I explain further?

Answer 4

it's -10 * 12

then 2/3 * y

that's cross-multiplying

Answer 5

basically write up you're equation as
-10 over 2/3 is equal to y over 12
then put an x across the equal sign and multiply the number at each end of the lines on the x. Is that easier to understand?

Answer 6

got it?

Answer 7

did you get it?
