2a+c=100-5b
Ikkala tarafdan 5b ni ayirish.
2a=100-5b-c
Ikkala tarafdan c ni ayirish.
2a=100-c-5b
Tenglama standart shaklda.
\frac{2a}{2}=\frac{100-c-5b}{2}
Ikki tarafini 2 ga bo‘ling.
a=\frac{100-c-5b}{2}
2 ga bo'lish 2 ga ko'paytirishni bekor qiladi.
a=-\frac{c}{2}-\frac{5b}{2}+50
100-5b-c ni 2 ga bo'lish.
5b+c=100-2a
Ikkala tarafdan 2a ni ayirish.
5b=100-2a-c
Ikkala tarafdan c ni ayirish.
5b=100-c-2a
Tenglama standart shaklda.
\frac{5b}{5}=\frac{100-c-2a}{5}
Ikki tarafini 5 ga bo‘ling.
b=\frac{100-c-2a}{5}
5 ga bo'lish 5 ga ko'paytirishni bekor qiladi.
b=-\frac{c}{5}-\frac{2a}{5}+20
100-2a-c ni 5 ga bo'lish.
