Answer:
x = 0, y = 2
x = 8/3, y = 0
x = 1, y = 5/4
x = 4/3, y = 1
Step-by-step explanation:
1) Let x = 0,
3(0) + 4y = 8 --> 4y = 8
y = 2
x = 0, y = 2
2) Let y = 0,
3x + 4(0) = 8 --> 3x = 8
x = 8/3
x = 8/3, y = 0
3) Let x = 1,
3(1) + 4y = 8 --> 4y = 5
y = 5/4
x = 1, y = 5/4
4) Let y = 1,
3x + 4(1) = 8 --> 3x = 4
x = 4/3
x = 4/3, y = 1
