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+y=4;2x+2y=-4 | | (6x^2-7x^2);-(2x^2-x^3) | | 3x+2y=0;-x+y=10 | | 2x+3y=13;-6x+4y=0 | | x=-3y-13;2x+2y=-6 | | y=2x+5;y=3x+4 | | y=3x-2;y=3x+4 | | 3x-3y=-23;x+3y=-1 | | 3x-2y=10;2x+3y=-2 | | 4x+5y=15;6x-4y=11 | | 3x+2y=-9;-10x+5y=-5 | | x-8y=18;-16x+16y=-8 | | 7x+15y=32;x-3y=20 | | 3x-10y=-25;4x+40y=20 | | 2x-3y+61;2x+y=-7 | | 7x+2y=10;-7x+y=-9 | | 3x-4y=7;2x-2y=5 | | x+y=1;x-y=5 | | y=0.50x+35;y=0.50x+35 | | 3x+4y=18;3x-4y=-6 | | -2x+y=-4;y=1/2x-1 | | 3x-5y=-7;-5x+7y=13 | | y=10x-1;y=-8x+17 | | 6x+2y=2;2-6x=y | | 6x+2y=2;4x-3y=11 | | y=-2x+3;3x-2y=8 | | x+y=4;y=2x+1 | | 2x-y=7;5x+y=21 | | 2x-3y=19;-3x-2y=-9 | | -3x+5y=15;6x-7y=-21 | | -9x+7y=-2;5x+6y=11 | | -3x-5y=21;5x+4y=4 |
