If it's not what You are looking for type in the system of equations solver your own equations and let us solve it.
Remember to put linear equations with variables x and y.
for example:
2x+y=8
x+3y=14
| 2x-y=-5;3x+y=0 | | 4x+3y=-5;x-3y=-20 | | 2x+2y=4;3x-2y=11 | | 4x+5y=-28;x-5y=18 | | 4x-2y=20;3x-y=-1 | | 2x+y=-4;3x-y=-1 | | 4x-4y=20;3x+4y=15 | | 2x+5y=-1;x-5y=-8 | | 3x-5y=-7;x=3y-2 | | 2x+2w=24;x=2w | | 3x-2y=4;y=-3x+7 | | x-4y=2;y=3x+5 | | x-2y=-3;y=-x+3 | | 3x-4y=-3;y=-3x-3 | | 3x+4y=-20;y=x+2 | | x+2y=-5;y=3x-13 | | y=4x+3;y=5x | | y=3x-2;y=4x | | y=x+5;y=2x | | x=y+7;4y=x+2 | | 6x+3y=1;y=-2x+1 | | 5x-10y=-4;5x+10y=-4 | | 5x-10y=-4;5x-10y=-2 | | 5x-10y=-4;15x-30y=-12 | | 5x-10y=-4;x+8y=-2 | | 5x-4y=4;5x-4y=8 | | 3x+4y=4;9x+12y=3 | | 2x-2y=2;4x-4y=-2 | | 3x-5y=5;12x-20y=4 | | 2x-3y=-8;8x-12y=-32 | | 3x+2y=7;-3x-2y=-7 | | 4x-y=12;-16x+4y=-48 |
