Answer:

x = 3

y = -2

Step-by-step explanation:

First, let's solve for y in the top equation:

  • 4x + 5y = 2
  • 5y = 2 - 4x
  • y = 0.4 - 0.8x

Now, plug it in in the second equation:

  • 2x + 3(0.4 - 0.8x) = 0
  • 2x + 1.2 - 2.4x = 0
  • -0.4x = -1.2
  • x = 3

We can continue solving for y:

  • 2(3) + 3y = 0
  • 6 + 3y = 0
  • 3y = -6
  • y = -2
