123. Решите уравнение: 1) 8 (x – 13) = 48; 2) 18 (x + 14) = 378; 3) 16 (4x - 26) = 224; 4) 9 (152-7x) = 927.

Математика 1) $$8(x - 13) = 48$$ $$x - 13 = 6$$ $$x = 19$$ <strong>Ответ: x = 19</strong> 2) $$18(x + 14) = 378$$ $$x + 14 = 21$$ $$x = 7$$ <strong>Ответ: x = 7</strong> 3) $$16(4x - 26) = 224$$ $$4x - 26 = 14$$ $$4x = 40$$ $$x = 10$$ <strong>Ответ: x = 10</strong> 4) $$9(152 - 7x) = 927$$ $$152 - 7x = 103$$ $$-7x = -49$$ $$x = 7$$ <strong>Ответ: x = 7</strong>
