Question

Solve for m in the following equation:
y = 3mx-4

Answer 1

Explanation:

`y = 3m * - 4 \\ y = - 12m \\ (y)/( - 12) = ( - 12m)/( - 12) \\ m = ( y)/( - 12)`

Answer 2

m =
`(y+4)/(3x)`

Explanation:

y = 3mx - 4 ( add 4 to both sides )

y + 4 = 3mx ( isolate m by dividing both sides by 3x )

`(y+4)/(3x)` = m
