Answer:
Step-by-step explanation:
3x - 4y = 9...........(1)
2x + 8y = 6..........(2)
Multiply (1) by 2 and (2) by 3
6x - 8y = 18.........(3)
6x + 24y = 18......(4)
Subtracting (3) from (4)
24y - (-8y) = 18 - 18
24y + 8y = 0
32y = 0
y = 0/32
y = 0
Substituting y = 0 into (1)
3y - 4y = 9
3y - 4(0) = 9
3y = 9
y = 9/3
y = 3
