Question

One solution, infinite, or no solution

22. Y=x+3
y=x-1

23. y=2x-1
3y=6x-5

24.3x+y=2
4y=12-12x

26.y=2x-2
2y=4x-4

27. y-x=5
3y=3x+15

28. 2x+2y=4
12-3x=3y

Answer 1

Please help

Answer 2

Ok thanks

Answer 3

so for 22 would it be no solution because earlier the lines didn't intersect?

Answer 4

Yes

Answer 5

Thanks

Answer 6

first equation y = 2x -2
divided by 2 the 2nd one y = 2x -2
again , let them equal, so 2x -2 =2x -2 or -2 =-2 , bingo, it's always right for any x. so, the conclusion is infinite solution, whatever x is, I always have -2 = -2 .
Make sense to you?
