Answer 2

Answer:

The solution is x = 0.25, y = -0.20.

or you can write it as (0.25, -0.20).

Step-by-step explanation:

4x + 5y = 0

8x - 15y = 5

Multiply the first equation by 3:

12x + 15y = 0     Now add this to the second equation:

20x = 5

x = 0.25.

Now substitute for x in equation 1:

4(0.25) + 5y = 0

1 + 5y = 0

5y = -1

y = -0.20.
