Решите уравнения:(x+63)-17=76 (x+81)+13=101 (143-y)-45=37 (24+x)-21=10 (x+15)-8=17

Решаем уравнения с одной переменной:

1) (x + 63) - 17 = 76;

x + 63 - 17 = 76;

x + 46 = 76;

x = 76 - 46;

x = 30;

2) (x + 81) + 13 = 101;

x + 81 = 101 - 13;

x + 81 = 88;

x = 88 - 81;

x = 7;

3) (143 - y) - 45 = 37;

143 - y = 37 + 45;

143 - y = 82;

y = 143 - 82;

y = 61;

4) (24 + x) - 21 = 10;

24 + x = 10 + 21;

24 + x = 31;

x = 31 - 24;

x = 7;

5) (x + 15) - 8 = 17;

x + 15 = 17 + 8;

x + 15 = 25;

x = 25 - 15;

x = 10.
