Question

Two systems of equations are given below. For each system, choose the best description of its solution. If applicable, give the solution -2x+y+6=0 2x-y=6 1.The system has no solution 2.The system has a unique solution: (x,y) 3.The system has infinitely many solutions. they must satisfy the following equation y=

Answer 1

-2x+y+6=0
2x-y=6

Well see that both x's cancel each other out? and so do the y's actually.. I'd say the first option because it'd just be 6 = 0 and 6 .. so I'm assuming it doesn't have a soultion

Answer 2

Thanks! ill try it out

Answer 3

I've never seen a system of equations with a constant on the left side, for #2 I'm kinda ehh on it because it say "unique solution" not sure what it means by unique.. because the left side has a constant?
