Question

Va rog cu rezolvările nu doar răspunsurile la aceste exercitii:) x+0,13=1 x+3,85=7,2. 5,7+x=9,2. 9,5+x=10. x+3=8,25. x+17,39=153,6. x-5,7=1,9. 17,3-x=3,8. x-3,24=0,157 5,4-x=4,32. x-13,2=9,84. 13,2-x=9,845. x•3,2=22,08. 0,2•x=1,88. 5,6•x=16,8. x•4=0,6. x•2,13=14,91. 15,3•x=15,3.

Answer 1

x+0,13=1 => x=1-0,13=0,87

x+3,85=7,2. => x=7,2-3,85=3,35
5,7+x=9,2. => x= 9,2-5,7=3,5

Answer 2

1)x=1-0,13
   x=0,87
2)x=7,2-3,85
    x=3,35
3)x=9,2-5,7
    x=3,5 etc
