Question

Y+27y=0,952 33m-m=102,4 2,7x-1,3x+3,6x=2

Answer 1

y+27y=0,952

28у=0,952

у=0,952:28

у=0,034

 

  33m-m=102,4

32 м=102,4

м=3,2

 

2,7x-1,3x+3,6x=2

5х=2

х=2:5

х=0,4

Answer 2

у + 27у = 0.952        28у = 0.952   у = 0.952 : 28 =  0.034     Проверка : 0.034 + о.918 = 0.952

 

33m - m = 102.4        32m = 102.4     m = 102.4 : 32      m =  3.2

 

2.7х - 1.3х + 3.6х = 2        5х = 2        х = 2 : 5      х =  0.4
