5x+2y=29
x-y=-4
2x-y=-1
3x-y=2
5x+y=16
x-2y=1
5x+2y=16
-3x+4y=-7
3x+2y=19
5x-2y=5
7x-1/3-2(7y+3)/5=10/3
5x+2/4+3y-2/5=16/5

I'll show you how to do the first oner. You try the others using the same method.
5x +2y = 29
x - y = -4
Double the last equation (both sides)
2x -2y = -8
Add the first and third equations.
7x = 21
x = 3
5x +2y = 29
x - y = -4
Double the last equation (both sides)
2x -2y = -8
Add the first and third equations.
7x = 21
x = 3
