2y-7=-x^{2}
Ikkala tarafdan x^{2} ni ayirish. Har qanday sonni noldan ayirsangiz, o‘zining manfiyi chiqadi.
2y=-x^{2}+7
7 ni ikki tarafga qo’shing.
2y=7-x^{2}
Tenglama standart shaklda.
\frac{2y}{2}=\frac{7-x^{2}}{2}
Ikki tarafini 2 ga bo‘ling.
y=\frac{7-x^{2}}{2}
2 ga bo'lish 2 ga ko'paytirishni bekor qiladi.
