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
| y+9=3z;y=39-3z | | 6x-y=4;y=4x+2 | | 3x-2y=6;5x=5-28y | | 1/5x+1/2y=1/2;1/5x+2y=5 | | 2x+2y=6;5x-2y-1=0 | | 4x-y=50;24x+13y=870 | | -4x+5y=10;3x+8y=0 | | 1/3x+1/2y=3/2;1/3x+4y=19 | | 7x+9y=-3;x=13-8y | | (4p+5);2.6 | | 2x+5y=-4;3x-y=11 | | 6x-y=1;x+y=6 | | 8x-2y=12;y=4x+6 | | 15x-20y=-1;5y=-1+10x | | 4x+3y=-17;x=1-6y | | 2x+y=10;y=3x | | y=-2x+2;8x+y=8 | | x-2y=10;x+2y=-2 | | 1/2x+1/3y=-2/3;1/2x+3y=2 | | 4x-y=160;26x+14y=1860 | | 4x+3y=3;16x+12y=0 | | 10x-2y=0;-15x-4y=35 | | 1/3x+1/2y=-1/6;1/3x+4y=31/3 | | 10x-2y=0;-11x-4y=31 | | 4x+9y=-15;x=2-8y | | 40x-5y=45;y=8x+9 | | -15x-10y=1;5y=-1+10x | | 2x+5y=28;x=18-3y | | 3x+y=15;y=2x | | y=-3x+3;6x+y=6 | | y=-3x+3;6x | | x+y=3;y-x+3 |
