Answer 1

У системі рівнянь {6ху+х+у=−2ху, х+у=5 здійснено заміну а = ху, b = х + у. Щоб знайти нову систему рівнянь, підставимо ці заміни в початкову систему:

Після заміни а = ху, ми отримуємо: 6а + b = -2а (рівняння 1) І після заміни b = х + у, ми отримуємо: b = 5 (рівняння 2)

Таким чином, нова система рівнянь має вигляд: {6а + b = -2а {b = 5
