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
| 3x=15-6y;9x+18y=45 | | y=50x;y=-50x+2000 | | 2X^3+4X+7;-5X^2-2X-11 | | x=4-y;2y=1-5x | | -4x+8y=72;2x+2y=0 | | -4x+9y=-59;-2x+4y=-28 | | y=x+1;y=2x+4 | | 4x=6-y;2x=-4-4y | | -4x-16y=1;6x+24y=0 | | 2x-3y=4;3x-5y=4 | | y-4x=6;3y=12x+18 | | 3y=2x+1;y=x-1 | | 3x+y=-6;2x+2y=4 | | 6x+7y=-35;-4x-5y=25 | | 7x+5y=-25;5x-2y=10 | | 3x+2y=1;4x+6y=7 | | 2x+y=5;3x-2y=11 | | 2x+y=5;3x-2y-11 | | y=9+3z;y=51-3z | | 17x+15y=255;x+y=16 | | 4x-y=3y+7;x+8y=4 | | 2x+2y=1;1x+1y=2 | | x+y=2;2x+2y=1 | | 2x+2y=1;x+y=2 | | -y+2z=5;y-3z=2 | | 3x+y=2;x+5y=1 | | 3x+y=2;2y=6 | | 6x+3y=2;5x+2y=5 | | x+y=3;2x+3y=2 | | 2x-y=12;x=-2y+3 | | x/7+16;x=14 | | 2x+5y=1;4x-5y=17 |
