Question

What is the value of x in the equation one-fifthx – two-thirdsy = 30, when y = 15?

Answer 1

the answer is D. 200

Answer 2

The value of x is 200.

Explanation:

Given equations,

`(1)/(5)x-(2)/(3)y=30----(1)`

`y=15-----(2)`

By substituting the value of y from equation (2) in equation (1),

`(1)/(5)x-(2)/(3)* 15=30`

`(x)/(5)-2* 5=30`

`(x)/(5)-10=30`

`(x)/(5)=40`

`x=5* 40=200`

Hence, the value of x is 200.
