Question

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

Answer 1

Answer: x = 200

Step-by-Step Solution:

=> 1/5x - 2/3y = 30 ; when y = 15

Substitute the value of ‘y’ :-

1/5x - 2/3y = 30
x/5 - 2(15)/3 = 30
x/5 - 30/3 = 30
x/5 - 10 = 30
x/5 - 50/5 = 30
x - 50 = 30 * 5
x - 50 = 150
x = 150 + 50
=> x = 200

Therefore, x = 200

Answer 2

Substituting in y=15,

`(1)/(5)x-\frac{2}[3}(15)=30\\\\(1)/(5)x-10=30\\\\(1)/(5)x=40\\\\x=\boxed{200}`
