Question

(42+150: (2x+13))-5=240 ответ

Answer 1

Решение и ответ:

(42 + 150 ÷ (2x + 13)) - 5 = 240

42 + 150 ÷ (2x + 13) - 5 = 240

150 ÷ (2x + 13) + 37 = 240

150 ÷ (2x + 13) = 240 - 37

150 ÷ (2x + 13) = 203

2x + 13 = 150/203

2x = 150/203 - 13

2x = -2489/203

x = -2489/203 ÷ 2

x = -2489/406 = -6 53/406
