Решите уровнение: 1) 29x-11x=504 2) 6x+25x=1674 3) X + 35x=2808 4) 7x + 9x+32=272 5) 5y+7y-24=204 6) 24x-15+47=1919

Вычислим х в уравнениях.

1) 29 * x - 11 * x = 504;

18 * x = 504;

x = 504/18;

x = 28.

2) 6 * x + 25 * x = 1 674;

x * (6 + 25) = 1 674;

x * 31 = 1 674;

31 * x = 1 674;

x = 1 674/31;

x = 54.

3) X + 35 * x = 2 808;

36 * x = 2 808;

x = 2 808/36;

x = 78.

4) 7 * x + 9 * x + 32 = 272;

16 * x + 32 = 272;

16 * x = 272 - 32;

16 * x = 240;

2 * x = 30;

x = 30/2;

x = 15.

5) 5 * y + 7 * y - 24 = 204;

12 * y - 24 = 204;

12 * y = 204 + 24;

12 * y = 228;

6 * y = 114;

3 * y = 57;

y = 57/3;

y = 19.

6) 24 * x - 15 + 47 = 1 919;

24 * x = 1 919 + 15 - 47;

24 * x = 1 887;

x = 1 887/24;

x = 78.625.
