Ответ:
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.
