Step-by-step explanation:

We have,

  • x+3y=5
  • x=5-3y.............(1)

Also,

  • xy=-2.............(2)

Putting value of x in equation 2, we have

  • 5y-3y^2=2

Now solving the quadratic equation by middle term split,we have

y=2/3 or y=1.

  1. Solve after this yourself.
  2. Do not rely on others as it will take you out of competition.

Good luck!
