a uchun yechish
\left\{\begin{matrix}a=\frac{A+c}{5b+4c}\text{, }&b\neq -\frac{4c}{5}\\a\in \mathrm{R}\text{, }&b=-\frac{4c}{5}\text{ and }A=-c\end{matrix}\right,
A uchun yechish
A=-\left(c-4ac-5ab\right)
Baham ko'rish
Klipbordga nusxa olish
5ab+4ac-c=A
Tomonlarni almashtirib, barcha oʻzgaruvchi shartlar chap tomonga oʻtkazing.
5ab+4ac=A+c
c ni ikki tarafga qo’shing.
\left(5b+4c\right)a=A+c
a'ga ega bo'lgan barcha shartlarni birlashtirish.
\frac{\left(5b+4c\right)a}{5b+4c}=\frac{A+c}{5b+4c}
Ikki tarafini 5b+4c ga bo‘ling.
a=\frac{A+c}{5b+4c}
5b+4c ga bo'lish 5b+4c ga ko'paytirishni bekor qiladi.
