Answer:


x = 7

Explanation:

Given


(4)/(3)x - (1)/(3) = 9

Required

Solve for x


(4)/(3)x - (1)/(3) = 9

Add
(1)/(3) to both sides


(4)/(3)x - (1)/(3) + (1)/(3) = 9 + (1)/(3)


(4)/(3)x = 9 + (1)/(3)

Take LCM


(4)/(3)x = (27 + 1)/(3)


(4)/(3)x = (28)/(3)

Multiply both sides by
(3)/(4)


(3)/(4) * (4)/(3)x = (3)/(4) *(28)/(3)

Evaluate the left hand side


x = (3)/(4) *(28)/(3)


x = (28)/(4)

Divide 28 by 4


x = 7
