Answer:

$\boxed {x = 6}$

Explanation:

Solve for the value of
:

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

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

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

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

-Add
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
by
:

x = (12)/(2)

$\boxed {x = 6}$
