124,2:(98-(8х+76,52))=23

Question

124,2:(98-(8х+76,52))=23

Answer 1

124,2:23=(98-(8х+76,52))
124,2:23=5,4
8х+76,52=92,6
92,6-76,52=8х
16,08=8х
х=2,01
Все просто

Answer 2

124,2:(98-(8х+76,52))=23

124,2:(98-8х-76,52) = 23

124,2:(21,48-8х)= 23

21,48-8х = 124,2:23

21,48-8х = 5,4

-8х = 5,4-21,48

-8х = -16,08

х =-16,08:(-8)

х = 2,01

Проверяем:

124,2:(98-(8*2,01+76,52)) = 124,2:(98-(16,08+76,52))= 124,2:(98-92,6) = 124,2:5,4 = 23

Ответ: 2,01.
