Question

решить уравнение x:3*80=150. 300-x*4=256. 12*x+19=43

Answer 1

x : 3 * 80 = 150

х = 150 : 80 * 3

x = 1,875 * 3

x = 5,625

Ответ: 5,625

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

300 - x * 4 = 256

x * 4 = 300 - 256

x * 4 = 44

x = 44 : 4

x = 11

Ответ: 11

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

12 * x + 19 = 43

12 * x = 43 - 19

12 * x = 24

x = 24 : 12

x = 2

Ответ: 2
