C.

d. 6

Answer 1

`\boxed {x = 6}`

Explanation:

Solve for the value of
`x` :

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

-Switch sides, and let
`(2)/(3)x - 7` be on the left side and
`-3` on right side:

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

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

-Add
`7` to both sides:

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

`(2)/(3)x = 4`

-Multiply
`(3)/(2)` on both sides, which is the reciprocal of
`(2)/(3)` :

`x = 4 * ((3)/(2))`

`x = (12)/(2)`

-Divide
`12` by
`2`:

`x = (12)/(2)`

`\boxed {x = 6}`
