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
