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
| 4x-4y=12;8x+8y=-72 | | x+7y=61;x-3y=-29 | | x+7y=-39;5x+6y=-21 | | 3x+6y=-15;5x+8y=-17 | | -3x-4y=-2;-5x-2y=6 | | x+5y=8;3x+7y=0 | | x+2y=13;x-5y=-50 | | -8/5x-7/9y=278/45;4/7x+2/3y=128/21 | | x-5y=-2;x-y=2 | | x-3y=-26;-6x-y=4 | | 4x-9y=-48;y=-9x+62 | | -2x-9y=35;5x+9y=-20 | | 8x+3y=69;9x+7y=74 | | 2x-4y=4;4x-8y=8 | | x+4y=14;-3x-7y=-27 | | 4x+4y=16;-9x+y=4 | | 5x-2y=24;y=8x-23 | | 4x-9y=28;-5x+y=-35 | | -9x+2y=-87;-7x+6y=-81 | | -7x+2y=-75;y=6x-60 | | x-9y=-11;-5x+2y=12 | | (8^2-5x);(6x^2-8x^3) | | (8x2-5x3);-(6x2-8x3) | | 3x-2y=6;x-y=3 | | 5x-3y=4;2x+4y=1 | | 3x-2y=15;5x+3y=6 | | a+b=10;a-b=6 | | a+b=7;a-b=3 | | 6x+4y=13;y=5-5x | | 3x-y+1=0;3y=-2x-8 | | -2/3(6x+9);-3/4(8x-4) | | -7x+14y=28;-7x+11y=-5 |
