fy-10=y+90 eching

$$f y - 10 = y + 90$$

f uchun yechish

$$f=\frac{y+100}{y}$$

$$y\neq 0$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

10 ni ikki tarafga qo’shing.

$$fy=y+90+10$$

100 olish uchun 90 va 10'ni qo'shing.

$$fy=y+100$$

Tenglama standart shaklda.

$$yf=y+100$$

Ikki tarafini y ga bo‘ling.

$$\frac{yf}{y}=\frac{y+100}{y}$$

y ga bo'lish y ga ko'paytirishni bekor qiladi.

$$f=\frac{y+100}{y}$$

y uchun yechish

$$y=\frac{100}{f-1}$$

$$f\neq 1$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Ikkala tarafdan y ni ayirish.

$$fy-10-y=90$$

10 ni ikki tarafga qo’shing.

$$fy-y=90+10$$

100 olish uchun 90 va 10'ni qo'shing.

$$fy-y=100$$

y'ga ega bo'lgan barcha shartlarni birlashtirish.

$$\left(f-1\right)y=100$$

Ikki tarafini f-1 ga bo‘ling.

$$\frac{\left(f-1\right)y}{f-1}=\frac{100}{f-1}$$

f-1 ga bo'lish f-1 ga ko'paytirishni bekor qiladi.

$$y=\frac{100}{f-1}$$
