5x=40+2y
2y ni ikki tarafga qo’shing.
5x=2y+40
Tenglama standart shaklda.
\frac{5x}{5}=\frac{2y+40}{5}
Ikki tarafini 5 ga bo‘ling.
x=\frac{2y+40}{5}
5 ga bo'lish 5 ga ko'paytirishni bekor qiladi.
x=\frac{2y}{5}+8
40+2y ni 5 ga bo'lish.
-2y=40-5x
Ikkala tarafdan 5x ni ayirish.
\frac{-2y}{-2}=\frac{40-5x}{-2}
Ikki tarafini -2 ga bo‘ling.
y=\frac{40-5x}{-2}
-2 ga bo'lish -2 ga ko'paytirishni bekor qiladi.
y=\frac{5x}{2}-20
40-5x ni -2 ga bo'lish.
