x/4-y/6 = 3
x/2-y = -2]×1/2 = x/4-y/2 = -1
x/4-y/6 = 3-----(1)
x/4-y/2 = -1-----(2)
subtract (2) from (2)
2y/6= 4
y = 4×6/2
y = 12
put the value of y in 1 equation
x/4-y/6 = 3
x/4-(12)/6 = 3
x/4 - 2 = 3
x/4 = 3+2
x/4 = 5
x = 5×4=20
x/2-y = -2]×1/2 = x/4-y/2 = -1
x/4-y/6 = 3-----(1)
x/4-y/2 = -1-----(2)
subtract (2) from (2)
2y/6= 4
y = 4×6/2
