5-9ia=a_{1}

Tomonlarni almashtirib, barcha oʻzgaruvchi shartlar chap tomonga oʻtkazing.

-9ia=a_{1}-5

Ikkala tarafdan 5 ni ayirish.

\frac{-9ia}{-9i}=\frac{a_{1}-5}{-9i}

Ikki tarafini -9i ga bo‘ling.

a=\frac{a_{1}-5}{-9i}

-9i ga bo'lish -9i ga ko'paytirishni bekor qiladi.

a=\frac{ia_{1}}{9}-\frac{5}{9}i

a_{1}-5 ni -9i ga bo'lish.

a_{1}=5-9ia

-9i hosil qilish uchun -1 va 9i ni ko'paytirish.
