Answer:
Subtract the first equation from the second equation.
Explanation:
Subtract the first equation from the second equation.
If we do so, 'x' will be eliminated and we will get the value of y
3x + 4y = 12 --------------(I)
3x = 2y - 8 -------------(II)
3x + 4y - 3x = 12 - (2y - 8)
3x - 3x +4y = 12 -2y +8
4y = 12 + 8 - 2y
4y +2y = 20
6y = 20
y = 20/6
y = 10/3
