لحل نظام المعادلات التالي باستخدام طريقة المحددات:

{5x−2y=−33x−y=3\begin{cases} 5x - 2y = -3 \\ 3x - y = 3 \end{cases}
  1. حساب محدد النظام Δ\Delta.

    Δ=∣5−23−1∣=(5)(−1)−(−2)(3)=−5−(−6)=−5+6=1\Delta = \begin{vmatrix} 5 & -2 \\ 3 & -1 \end{vmatrix} = (5)(-1) - (-2)(3) = -5 - (-6) = -5 + 6 = 1
  2. حساب محدد xx وهو Δx\Delta_x.

    Δx=∣−3−23−1∣=(−3)(−1)−(−2)(3)=3−(−6)=3+6=9\Delta_x = \begin{vmatrix} -3 & -2 \\ 3 & -1 \end{vmatrix} = (-3)(-1) - (-2)(3) = 3 - (-6) = 3 + 6 = 9
  3. حساب محدد yy وهو Δy\Delta_y.

    Δy=∣5−333∣=(5)(3)−(−3)(3)=15−(−9)=15+9=24\Delta_y = \begin{vmatrix} 5 & -3 \\ 3 & 3 \end{vmatrix} = (5)(3) - (-3)(3) = 15 - (-9) = 15 + 9 = 24
  4. إيجاد قيم xx و yy.

    x=ΔxΔ=91=9x = \frac{\Delta_x}{\Delta} = \frac{9}{1} = 9 y=ΔyΔ=241=24y = \frac{\Delta_y}{\Delta} = \frac{24}{1} = 24

    مجموعة الحل هي:

    S={(9,24)}\boxed{S = \{(9, 24)\}}
