Решите уравнения х+(-5)=2 8+у=-3 14+х=-6 -6+х=2 у-7=-13 х+11=-4

1) х + (-5) = 2.x - 5 = 2.x = 2 + 5.x = 7.2) 8 + у = -3.y = -3 - 8.y = -11.3) 14 + х = -6.x = -6 - 14.x = -20.4) -6 + х = 2.x = 2 + 6.x = 8. 5) у - 7= -13.y = - 13 + 7.y = -8.6) х + 11 = -4.x = -4 - 11.x = -15.Ответ: 1) x = 7; 2) y = -11; 3) x = -20; 4) x = 8; 5) y = -8; 6) x = -15.
