X = 4 + 2y

1/2(4+2y) + 1/3y = 2
2 + y + 1/3y = 2
y + 1/3y = 2 - 2
4/3y = 0
y = (4/3)0
y = 0

x - 2(0) = 4
x = 4

X = 4 + 2y

 \frac{1}{2} ( 4 + 2y ) +  \frac{1}{3}y  = 2
2 + y +  \frac{1}{3}y  = 2
 \frac{4}{3}y = 2 - 2
y =  \frac{3}{4}  × 0
y = 0

x - 2(0) = 4
x - 0 = 4
x = 4 + 0
x = 4

x = 4   y = 0
