Question

What is the value of x in the equation 1/5x – 2/3y = 30, when y = 15?

A.4

B.8

C.80

D. 200

Answer 1

D

Explanation:

Providing it is written as 1 * x / 5 - 2*y / 3 = 30, it can be solved this way.

x/5 - 2*15/3 = 30

x/5 - 10 = 30

x/5 = 30 + 10

x/5 = 40

(x/5)*5 = 40*5

x = 200

Answer D
