ab+4a-9=96-4b
Ikkala tarafdan 4b ni ayirish.
ab+4a=96-4b+9
9 ni ikki tarafga qo’shing.
ab+4a=105-4b
105 olish uchun 96 va 9'ni qo'shing.
\left(b+4\right)a=105-4b
a'ga ega bo'lgan barcha shartlarni birlashtirish.
\frac{\left(b+4\right)a}{b+4}=\frac{105-4b}{b+4}
Ikki tarafini b+4 ga bo‘ling.
a=\frac{105-4b}{b+4}
b+4 ga bo'lish b+4 ga ko'paytirishni bekor qiladi.
ab+4b-9=96-4a
Ikkala tarafdan 4a ni ayirish.
ab+4b=96-4a+9
9 ni ikki tarafga qo’shing.
ab+4b=105-4a
105 olish uchun 96 va 9'ni qo'shing.
\left(a+4\right)b=105-4a
b'ga ega bo'lgan barcha shartlarni birlashtirish.
\frac{\left(a+4\right)b}{a+4}=\frac{105-4a}{a+4}
Ikki tarafini a+4 ga bo‘ling.
b=\frac{105-4a}{a+4}
a+4 ga bo'lish a+4 ga ko'paytirishni bekor qiladi.
