Baham ko'rish
Klipbordga nusxa olish
DE_{9}+5=D^{2}E
D^{2} hosil qilish uchun D va D ni ko'paytirish.
D^{2}E=DE_{9}+5
Tomonlarni almashtirib, barcha oʻzgaruvchi shartlar chap tomonga oʻtkazing.
\frac{D^{2}E}{D^{2}}=\frac{DE_{9}+5}{D^{2}}
Ikki tarafini D^{2} ga bo‘ling.
E=\frac{DE_{9}+5}{D^{2}}
D^{2} ga bo'lish D^{2} ga ko'paytirishni bekor qiladi.
