Question

When isolating a variable in the equation -3y=2x-7, how do you get rid of the -3 in front of the y?

Answer 1

Answer: You divide both sides by -3.

Explanation:

We're asked to solve the equation:
`\sf{-3y=2x-7}`.

To do this, divide both sides by -3:

`\sf{-3y=2x-7}`

`\sf{y=\cfrac{2x-7}{-3}`

Simplify

`\sf{y=-\cfrac{2x-7}{3}}`

Therefore, that's our answer.

Answer 2

divide both sides by - 3

Explanation:

given the equation

- 3y = 2x - 7

to isolate y then divide both sides by - 3

`(-3)/(-3)` y =
`(2x-7)/(-3)` , that is

y =
`(2x-7)/(-3)`

or

y =
`(2)/(-3)` x +
`(-7)/(-3)` = -
`(2)/(3)` x +
`(7)/(3)`
