{l}{2dy*4x=-20}{6x=4y+10}-ஐ தீர்க்கவும்

$$\left. \begin{array} { l } { 2 d y \cdot 4 x = - 20 } \\ { 6 x = 4 y + 10 } \end{array} \right.$$

x, y-க்காகத் தீர்க்கவும் (சிக்கலான தீர்வு)

$$x=-\frac{\sqrt{25d^{2}-60d}}{6d}+\frac{5}{6}\text{, }y=-\frac{\sqrt{25d^{2}-60d}}{4d}-\frac{5}{4}$$

$$x=\frac{\sqrt{25d^{2}-60d}}{6d}+\frac{5}{6}\text{, }y=\frac{\sqrt{25d^{2}-60d}}{4d}-\frac{5}{4}\text{, }d\neq 0$$

x, y-க்காகத் தீர்க்கவும்

$$\left\{\begin{matrix}x=-\frac{\sqrt{25d^{2}-60d}}{6d}+\frac{5}{6}\text{, }y=-\frac{\sqrt{25d^{2}-60d}}{4d}-\frac{5}{4}\text{; }x=\frac{\sqrt{25d^{2}-60d}}{6d}+\frac{5}{6}\text{, }y=\frac{\sqrt{25d^{2}-60d}}{4d}-\frac{5}{4}\text{, }&d<0\\x=\frac{-\sqrt{25-\frac{60}{d}}+5}{6}\text{, }y=\frac{-\sqrt{25-\frac{60}{d}}-5}{4}\text{; }x=\frac{\sqrt{25-\frac{60}{d}}+5}{6}\text{, }y=\frac{\sqrt{25-\frac{60}{d}}-5}{4}\text{, }&d\geq \frac{12}{5}\end{matrix}\right.$$
