Покрокове пояснення:

Одне з можливих лінійних рівнянь з двома змінними, розв'язком якого є пара чисел (2; -1), має вигляд:

y + 3x = -7

Для перевірки, підставимо значення x = 2 та y = -1:

-1 + 3(2) = 5

Отже, точка (2; -1) є розв'язком даного рівняння, оскільки при цих значеннях x та y ліва та права частини рівності будуть дорівнювати одне одному.
