a) 98- ((45+x) - 38 )= 42
б) 25*(328-8*x)= 5400
​

Answer 1

Ответ:

Пошаговое объяснение:

a) 98- ((45+x) - 38 )= 42

(45 + x) - 38 = 98 - 42

45 + x - 38 = 56

7 + x = 56

x = 56 - 7

x = 49

====================

б) 25*(328-8*x)= 5400

328 - 8x = 5400:25

328 - 8x = 216

8x = 328 - 216

8x = 112

x = 112 : 8

x = 14
