Answer:
y = 6/5, x = 19/5
Step-by-step explanation:
Let's isolate a variable. Let's say 'x'
x + y = 5
x = 5 - y
2x - 3y = 4
2x = 4 + 3y
x = (4 + 3y) / 2
From this, we can say
5 - y = (4 + 3y) / 2
10 - 2y = 4 + 3y
10 - 4 = 3y + 2y
6 = 5y
y = 6/5
x + y = 5
x + (6/5) = 5
x = (5/1) - (6/5)
x = (25 - 6)/5
x = 19/5
