\(y-3xy+2x=4\)
\(\Leftrightarrow3y-9xy+6x=12\)
\(\Leftrightarrow3y\left(1-3x\right)-2\left(1-3x\right)=10\)
\(\Leftrightarrow\left(1-3x\right)\left(3y-2\right)=10\)
1-3x | -10 | -5 | -2 | -1 | 1 | 2 | 5 | 10 |
3y-2 | -1 | -2 | -5 | -10 | 10 | 5 | 2 | 1 |
x | 11/3 | 2 | 1 | 2/3 | 0 | -1/3 | -4/3 | -3 |
y | 1/3 | 0 | -1 | -8/3 | 4 | 7/3 | 4/3 | 1 |
Vậy \(\left(x;y\right)=\left(2;0\right);\left(1;-1\right);\left(0;4\right);\left(-3;1\right)\)
