Answer:


\boxed {x = -75}

Explanation:

Solve for the value of
x:


(1)/(3)x + 2 = (1)/(5)x - 8

-Take
(1)/(5)x and subtract it from
(1)/(3)x:


(1)/(3)x + 2 - (1)/(5)x = (1)/(5)x - (1)/(5)x - 8


(2)/(15)x + 2 = -8

-Subtract
2 to both sides:


(2)/(15)x + 2 - 2 = -8 - 2


(2)/(15)x = -10

-Multiply both sides by
(15)/(2), which is the reciprocal of
(2)/(15).


x = -10 * ((15)/(2))


x = (-10 * 15)/(2)


x = (-150)/(2)

-Divide
-150 by
2:


x = (-150)/(2)


\boxed {x = -75}

So, the value of
x is
-75.
