Решим уравнения:
- $$29x - 11x = 504$$
$$18x = 504$$
$$x = 504 : 18$$
$$x = 28$$
- $$6x + 25x = 1674$$
$$31x = 1674$$
$$x = 1674 : 31$$
$$x = 54$$
- $$x + 35x = 2808$$
$$36x = 2808$$
$$x = 2808 : 36$$
$$x = 78$$
- $$11x + 8x = 456$$
$$19x = 456$$
$$x = 456 : 19$$
$$x = 24$$
- $$38x - 14x = 1608$$
$$24x = 1608$$
$$x = 1608 : 24$$
$$x = 67$$
- $$x + 27x = 1204$$
$$28x = 1204$$
$$x = 1204 : 28$$
$$x = 43$$
Ответ: x = 28; x = 54; x = 78; x = 24; x = 67; x = 43
