Question

daca se asaza cate 3 flori intr-o vaza raman 8 flori fara vaza. daca se asaza cate 5 flori intr-o vaza raman 2 vaze goale. cate vazw si cate flori sunt

Answer 1

a*3=f+8
f=a*3+8....=>a>8....=>a=9
f=9*3+8
f=27+8
f=35 (flori)

a=> vaze
a=9

9-2=7 vaze a cate 5 flori si 2 raman goale
35:9=3 rest 8 .....adica....3*9=27 flori in 9 vaze a cate 3 flori in vaza +8 flori
                                       ramase fara vaza...=35 flori in total

Answer 2

3x+8=5x-10=>18=2x=>x=9=>3*9+8=27+8=35flori
35:5=7 vaze pline + 2 vaze goale = 9 vaze(in total) 
Verificare 9*3+8=35 <=> 35=35 Adevarat
