Question

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

Answer 1

Answer:

The value of x is 200.

Step-by-step explanation:

Given equations,

$\frac{1}{5}x-\frac{2}{3}y=30----(1)$

$y=15-----(2)$

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

$\frac{1}{5}x-\frac{2}{3}\times 15=30$

$\frac{x}{5}-2\times 5=30$

$\frac{x}{5}-10=30$

$\frac{x}{5}=40$

$x=5\times 40=200$

Hence, the value of x is 200.
