Question

Solve each equation for the specified variable 2d-3f=9 solve for f

Answer 1

`f=(2)/(3) d-3`

Explanation:

`2d-3f=9`

Solve for
`f` variable.

Subtract
`2d` on both sides.

`2d-3f-2d=9-2d`

`-3f=9-2d`

Divide both sides by
`-3`.

`(-3f)/(-3) =(9-2d)/(-3)`

`f=(-9)/(3) +(2)/(3) d`

`f=-3+(2)/(3) d`

Answer 2

f = 2/3d -3

Explanation:

2d-3f=9

Subtract 2d from each side

2d-2d-3f=9-2d

-3f = 9-2d

Divide by -3

-3f/-3 = 9/-3 -2d/-3

f = -3 +2/3 d

f = 2/3d -3
