7x-8z=65-4y
Ikkala tarafdan 4y ni ayirish.
7x=65-4y+8z
8z ni ikki tarafga qo’shing.
7x=65+8z-4y
Tenglama standart shaklda.
\frac{7x}{7}=\frac{65+8z-4y}{7}
Ikki tarafini 7 ga bo‘ling.
x=\frac{65+8z-4y}{7}
7 ga bo'lish 7 ga ko'paytirishni bekor qiladi.
4y-8z=65-7x
Ikkala tarafdan 7x ni ayirish.
4y=65-7x+8z
8z ni ikki tarafga qo’shing.
4y=65+8z-7x
Tenglama standart shaklda.
\frac{4y}{4}=\frac{65+8z-7x}{4}
Ikki tarafini 4 ga bo‘ling.
y=\frac{65+8z-7x}{4}
4 ga bo'lish 4 ga ko'paytirishni bekor qiladi.
y=-\frac{7x}{4}+2z+\frac{65}{4}
