2x-3y=42
Tenglamaning ikkala tarafini 6 ga, 3,2 ning eng kichik karralisiga ko‘paytiring.
2x=42+3y
3y ni ikki tarafga qo’shing.
2x=3y+42
Tenglama standart shaklda.
\frac{2x}{2}=\frac{3y+42}{2}
Ikki tarafini 2 ga bo‘ling.
x=\frac{3y+42}{2}
2 ga bo'lish 2 ga ko'paytirishni bekor qiladi.
x=\frac{3y}{2}+21
42+3y ni 2 ga bo'lish.
2x-3y=42
Tenglamaning ikkala tarafini 6 ga, 3,2 ning eng kichik karralisiga ko‘paytiring.
-3y=42-2x
Ikkala tarafdan 2x ni ayirish.
\frac{-3y}{-3}=\frac{42-2x}{-3}
Ikki tarafini -3 ga bo‘ling.
y=\frac{42-2x}{-3}
-3 ga bo'lish -3 ga ko'paytirishni bekor qiladi.
y=\frac{2x}{3}-14
42-2x ni -3 ga bo'lish.
