Solve using the elimination method. If the system has no solution or an infinite number of solutions, state this.
2x  8y = 22
6x  y = 20

2x  8y = 22 ...(1)
6x  y = 20 ...(2)
(2)3(1)
23y = 46
y = 2 ...(3)
substitute (3) in(2)
6x +2 = 20
x=3 ...(4)
substitute (3) and (4) in (1)
6 + 16 =22 = RHS
So
x=3, y=2
