Question

Solve for x and y given
3/5y + 2/5x = 500
and 2/5y + 3/5x = 400.
Plzzz answer fastt​

Answer 1

Step-by-step explanation:

3/5y+2/5x = 500

=> 2/x + 3/y = 2500 ..........(1)

2/5y + 3/5x = 400

=> 3/x + 2/y = 2000...........(2)

3×(1) -2×(2)

=> 5/y = 3500

=> y = 5/3500 = 1 / 700

substituting the value of y in (1)

2/x+3×700 = 2500

=> 2/x = 400

=> x = 2/400= 1 / 200

therefore,

x = 1/200

y = 1/700

hope this helps you
