a+ab=25-b
Ikkala tarafdan b ni ayirish.
\left(1+b\right)a=25-b
a'ga ega bo'lgan barcha shartlarni birlashtirish.
\left(b+1\right)a=25-b
Tenglama standart shaklda.
\frac{\left(b+1\right)a}{b+1}=\frac{25-b}{b+1}
Ikki tarafini 1+b ga bo‘ling.
a=\frac{25-b}{b+1}
1+b ga bo'lish 1+b ga ko'paytirishni bekor qiladi.
b+ab=25-a
Ikkala tarafdan a ni ayirish.
\left(1+a\right)b=25-a
b'ga ega bo'lgan barcha shartlarni birlashtirish.
