Indicate whether each system is independent, inconsistent, or dependent
x+3 (y-1) = 11
2 (x-y) + 8y =28
x+3 (y-1) = 11 ..................(1)
2 (x-y) + 8y =28 ..................(2)
Solution. Simplifying (1), we get
x+3y=14 .................(3)
We multiply by 0.5 on both sides of (2), we get
x+3y=14 ..............(4)
(3) and (4) are the same, so we conclude that the system is dependent
