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
| -7x+5y=-1;4x-y=0 | | 1x-4y=28;2x-y=12 | | 2x-5y=20;3x-y=10 | | 2s-3t=42;3s+2t=24 | | 4x+2y=8;-2x+5y=8 | | 4x+3y=90;3x+4y=85 | | 2x=3y;5y=6x+12 | | x/4+1,5y;2+2x+y/6 | | 10/21x+2/10y=80;x+y=255 | | y-2x=0;3x+7y=17 | | -3x-10y=9;14x+18y=-22 | | k^5;k^3 | | -16x+2y=18;8x-4y=12 | | y+1=2x-1;y-1=x+1 | | y=2x-2;y-1=x+1 | | (9x-4);(4x+5) | | 2x+7y=-20;x-5y=-10 | | 2x+y=21;7x-2y=90 | | 8x-6y=16;12x-9y=24 | | 2x-3y=2;5x-3y=14 | | 2x-3y+2;5x-3y=14 | | 3x+y=19;x+3y=1 | | 2x+3y-10=0;4x-3y-2=0 | | x^2+y^2+x+3y+2=0;x-y=0 | | 5x^2+20x+9y-7=0;5x^2+10y^2+20x-y-67=0 | | 3x-2y=-15;x-(2/3)y=-5 | | 3y^2+10y;2y | | -2x+5y=-31;y=3x-14 | | -5x-3y=11;-7x+4y=-11 | | 3x-4y=10;30x-6y=-36 | | v+w=60;v-w=40 | | x+y=20;x-y=10 |
