Question

Oblicz liczbę x ( rozwiąż równania ):

a) x+12,83=22,1

b) 88,4 - x = 51,16

c) c - 19,415 = 21,11

Answer 1

 

x + 12,83 = 22,1 || - 12,83

x + 12,83 - 12,83 = 22,1 - 12,83

x = 9,27

 

88,4 - x = 51,16 || -88,4

-x = 51,16 - 88,4

-x = -37,24 ||*(-1)

x = 37,24

 

x - 19,415 = 21,11 ||+19,415

x = 21,11 + 19,415

x = 40,525
