1. Sorry forgot to put these 2 in as well-

What is the solution of the system?
5x-y =-7
3x-y=-2

What is the solution of the system?
5x+6y=20
9x+11y=32

2. For the first one, just subtract the two equations to get

2x = -5
and go from there

For the 2nd set, multiply them a bit to get

45x+54y = 180
45x+55y = 160
Now subtract to get
y = -20
and go from there
