Answer:
Explanation:
Multiply the top equation by 3.
3*(x - y)/3 = 0.5 * 3
(x - y) = 1.5
There is no single solution that satisfies this system. There infinitely many values for x and y that will work. The only restriction is that x - y = 1,5
So if you make y = 3
x - 3 = 1.5 Add 3 to both results
x - 3 + 3 = 1.5 + 3 Combine
x = 4.5
Infinitely many solutions exist.
