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
| x=3y-1;x+2y=9 | | y=2x;x+y=12 | | 5x+y=15;3x-2y=9 | | 5x+y=6;3x-3y=18 | | -x+2y=8;5x+6y=-8 | | 7x+4y=59;2x+6y=46 | | 4x+6y=9;12x+18y=27 | | 10x+5y=15;2x+5y=8 | | 9x+2y=20;6x-8y=4 | | a+s=17;a+s=305 | | -x+4y=2;4x+6y=36 | | x-y=6;x+y=-6 | | -7x+4y=-12;8x-4y=12 | | 9x+3y=15;y-x=5 | | 8x-2y=10;3x+y=2 | | -x+2y=9;4x+5y=3 | | x-y=6;x+3y=-6 | | 3x+6y=9;9x+18y=27 | | y=-x-2;y=2x-5 | | -x+3y=8;4x+5y=2 | | 9x+3y=84;9x-9y=72 | | 4x+y=6;3x-2y=10 | | 3x+2y=25;3x-9y=-63 | | -3+4y=-8;4x-4y=8 | | -3x-y=-20;4x+10y=18 | | 3x-3y=4;5x-2y=4 | | 12x+4y=9;-3x=y+6 | | 6x-7y=2;y=x-1 | | 3x-y=-4;x+y=0 | | 6x+y=-2;5x-2y=-98 | | 3x+4y=0;6x+8y=5 | | x-4y=-10;-x+6y=14 |
