Question

3) Aflati x din:
a) 15,23+(11,01+ x)=26,73
b)11193,001-(897,906 + x)=292,901
c) x + (15,1007 - 0,963)=15,0377

5) Rezolvati ecuatiile:
A) 63,56 + (27,45 - x)=77,019
b) x - (18,23 + 1,27)=15,64
c) (17,824 - x) + 1,172=10

Answer 1

a)11,01+x=26,73-15,23
   x=11,50-11,01
   x=0,49
b)11193,001-(897,906+x)=292,901
 - 897,906-x=292,901-11193,001
-897,906-x= -11099,900 deoarece peste tot avem " - " imultim cu : "-1"
809,906+x=11099,900
x=11099,900-809,906
x=10289,994
