x_{3}=-3x_{2}+6
Réitigh -3x_{2}-x_{3}+6=0 do x_{3}.
3x_{1}+4x_{2}+3\left(-3x_{2}+6\right)+5=0 x_{1}+x_{2}-3x_{2}+6+2=0
Cuir -3x_{2}+6 in ionad x_{3} sa dara agus sa tríú cothromóid.
x_{2}=\frac{3}{5}x_{1}+\frac{23}{5} x_{1}=-8+2x_{2}
Réitigh na cothromóidí seo do x_{2} agus x_{1} faoi seach.
x_{1}=-8+2\left(\frac{3}{5}x_{1}+\frac{23}{5}\right)
Cuir \frac{3}{5}x_{1}+\frac{23}{5} in ionad x_{2} sa chothromóid x_{1}=-8+2x_{2}.
x_{1}=-6
Réitigh x_{1}=-8+2\left(\frac{3}{5}x_{1}+\frac{23}{5}\right) do x_{1}.
x_{2}=\frac{3}{5}\left(-6\right)+\frac{23}{5}
Cuir -6 in ionad x_{1} sa chothromóid x_{2}=\frac{3}{5}x_{1}+\frac{23}{5}.
x_{2}=1
Ríomh x_{2} ó x_{2}=\frac{3}{5}\left(-6\right)+\frac{23}{5}.
x_{3}=-3+6
Cuir 1 in ionad x_{2} sa chothromóid x_{3}=-3x_{2}+6.
x_{3}=3
Ríomh x_{3} ó x_{3}=-3+6.
x_{2}=1 x_{3}=3 x_{1}=-6
Tá an córas réitithe anois.
