what is the value of y following system of the linear equation?
2x+6y=9 y=-1/2x+2
2x + 6y = 9 y = -1/2 x + 2
1/2 x + y = 2
4 * (1/2 x + y) = 2 * 4
2x + 4y = 8
2x + 6y = 9
-(2x + 4y = 8)
----------------------
2y = 1
2y = 1
y = 1/2 <<<<<<<<<<<
2x + 6y = 9
2x + 6(1/2) = 9
2x + 3 = 9
2x = 6
x = 3 <<<<<<<<<<<
