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
| 6x+y=2;6x+y+3=0 | | x+y=-4;x-y=0 | | x-2y=-9;5x+4y=25 | | x-2y=-9;3x+4y=25 | | 12x-y=1;28x+1/3y=1 | | 3x-12y=3;-2x+8y=5 | | 3x-12y=3;-2y+8y=5 | | 3x-12y=3;-12x+8y=5 | | 2x+5y=-6;2x-10/3y=-12 | | 4x-6y+3;3y-2x=3 | | 3x+4y=10;6x-4y=-8 | | X+y=5;X+y=-5 | | 2x+2y=4;-x+2y=4 | | 3x-5y=-16;2x-3y=-8 | | 3x+10y=23;5x+2y=55 | | 8x-4y=-76;5x+2y=-16 | | 2x+7y=10;x+3y=20 | | 2x+7y=0;x+3y=20 | | 5x+2y=4;4x+2y=6 | | -3x-4y=2;8y-6x-4 | | -6x-2y=18;8y=-24x-72 | | x+5y=5;5x-15y=9 | | 5x-8y=-17;-3x+4y=6 | | 2x+7y=0;5x-14y=0 | | 40=4x+10y;48=-6x-8y | | 1600+X=Y;Y/4-55=X | | x+6y=-43;6x-5y=70 | | 5x+32;-4x-22 | | 5x-4;5x+8 | | 0.8x+7.2;20x+32y=48 | | 5x-8;4x-7 | | 6x+13;2x+1 |
