Решите уравнени 8 (х-14=56 (46-х) * 19 = 418 9 (143-13 х) = 234 17 (5 х-16) = 138

1) 8 * (х - 14) = 56;

х - 14 = 56 : 8;

х - 14 = 7;

х = 7 + 14;

х = 21.

2) (46 - х) * 19 = 418;

46 - х = 418 : 19;

46 - х = 22;

46 - 22 = х;

х = 24.

3) 9 * (143 - 13 х) = 234;

143 - 13 х = 234 : 9;

143 - 13 х = 26;

143 - 26 = 13 х;

117 = 13 х;

х = 117 : 13;

х = 9.

4) 17 * (5 х - 16) = 138;

5 х - 16 = 138 : 17;

5 х - 16 = 8 2/17;

5 х = 8 2/17 + 16;

5 х = 24 2/17;

х = 24 2/17 : 5;

х = (24 * 17 + 2) / 17 : 5;

х = 410/17 * 1/5;

х = (5 * 82) / (17 * 5);

х = 82/17;

х = 4 (82 - 4 * 17) / 17;

х = 4 (82 - 68) / 17;

х = 4 14/17.
