-2D-4y=3-7c
Ikkala tarafdan 7c ni ayirish.
-2D=3-7c+4y
4y ni ikki tarafga qo’shing.
-2D=4y-7c+3
Tenglama standart shaklda.
\frac{-2D}{-2}=\frac{4y-7c+3}{-2}
Ikki tarafini -2 ga bo‘ling.
D=\frac{4y-7c+3}{-2}
-2 ga bo'lish -2 ga ko'paytirishni bekor qiladi.
D=\frac{7c}{2}-2y-\frac{3}{2}
3-7c+4y ni -2 ga bo'lish.
7c-4y=3+2D
2D ni ikki tarafga qo’shing.
7c=3+2D+4y
4y ni ikki tarafga qo’shing.
7c=4y+2D+3
Tenglama standart shaklda.
\frac{7c}{7}=\frac{4y+2D+3}{7}
Ikki tarafini 7 ga bo‘ling.
c=\frac{4y+2D+3}{7}
7 ga bo'lish 7 ga ko'paytirishni bekor qiladi.
