Как решить уравнение 87: (4x+5) = 3 17 * (3x-16) = 85 9 * (6x-13) = 153 3 * (8x+51) = 201 (46x-57) : 3=27 (19x+62) : 15=13

1) 87 : (4 * x + 5) = 3;

87 : 3 = 4 * x + 5;

4 * х = 29 - 5;

х = 24/4 = 6;

2) 17 * (3 * x - 16) = 85;

3 * x - 16 = 85/17;

3 * х = 5 + 16;

х = 21/3 = 7;

3) 9 * (6 * x - 13) = 153;

6 * x - 13 = 153/9;

6 * х = 17 + 13;

х = 30/6 = 5;

4) 3 * (8 * x + 51) = 201;

8 * x + 51 = 201/3;

8 * х = 67 - 51;

х = 16/8 = 2;

5) (46 * x - 57) : 3 = 27;

46 * x - 57 = 27 * 3;

46 * х = 81 + 57;

х = 138/46 = 3;

6) (19 * x + 62) : 15 = 13;

19 * x + 62 = 13 * 15;

19 * х = 195 - 62;

х = 133/19 = 7.
