5x=20+4y
4y ni ikki tarafga qo’shing.
5x=4y+20
Tenglama standart shaklda.
\frac{5x}{5}=\frac{4y+20}{5}
Ikki tarafini 5 ga bo‘ling.
x=\frac{4y+20}{5}
5 ga bo'lish 5 ga ko'paytirishni bekor qiladi.
x=\frac{4y}{5}+4
20+4y ni 5 ga bo'lish.
-4y=20-5x
Ikkala tarafdan 5x ni ayirish.
\frac{-4y}{-4}=\frac{20-5x}{-4}
Ikki tarafini -4 ga bo‘ling.
y=\frac{20-5x}{-4}
-4 ga bo'lish -4 ga ko'paytirishni bekor qiladi.
y=\frac{5x}{4}-5
20-5x ni -4 ga bo'lish.
