Question

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

Answer 1

Answer:

$\frac{1x}{5} - \frac{2y}{3} = 30 \\ \frac{3x - 10y }{15} = 30$

3x-10y=30×15

y=15

3x-10 (15)=450

3x-150=450

3x=450+150

3x=600

x=200

Answer 2

Answer:

wait...

Step-by-step explanation:

given --- y=15

by putting the value in equation

$\frac{1}{5} x - \frac{2}{3} y = 30 \\ \frac{x}{5} - \frac{2 \times 15}{3} = 30 \\ \frac{x}{5 } - 10 = 30 \\ \frac{x}{5} = 40 \\ x = 40 \times 5 \\ x = 200$

So the value of x is 200
