Q uchun yechish
\left\{\begin{matrix}Q=\frac{B}{hz+1}\text{, }&h=0\text{ or }z\neq -\frac{1}{h}\\Q\in \mathrm{R}\text{, }&B=0\text{ and }z=-\frac{1}{h}\text{ and }h\neq 0\end{matrix}\right,
B uchun yechish
B=Q\left(hz+1\right)
Baham ko'rish
Klipbordga nusxa olish
Q+Qzh=B
Tomonlarni almashtirib, barcha oʻzgaruvchi shartlar chap tomonga oʻtkazing.
\left(1+zh\right)Q=B
Q'ga ega bo'lgan barcha shartlarni birlashtirish.
\left(hz+1\right)Q=B
Tenglama standart shaklda.
\frac{\left(hz+1\right)Q}{hz+1}=\frac{B}{hz+1}
Ikki tarafini 1+zh ga bo‘ling.
Q=\frac{B}{hz+1}
1+zh ga bo'lish 1+zh ga ko'paytirishni bekor qiladi.
