Răspuns :
daca notam cu x primul nr si cu y al doilea⇒
x-y=747
y:x=6 rest 37 ⇔y=x.6+37
x-6x+37=747
-5x=747-37
-5x=710
x=-142
-142-y=747
-y=889
y=-889
(raman la parerea mea ca este ceva in neregula ca cele doua numere nu sunt naturale)
2. x-primul raft
y-al doilea raft
z- al treilea raft
x+y+z=153
y=z+5
y=x-8
exprimam pe z si x in functie de y si introducem inprima ecuatie
z=y-5
x=y+8
y+8+y+y-5=153
3y=150
y=50
x=50+8=58
z=50-5=45
3.x+y+z=710
y=15+2x
z=3y-25=20+6x
x+15+2x+20+6x=710
9x=710-35
9x=675
x=75
z=20+6x=20+75.6=470
y=15+2x=15+2.75=165
3. x-bile rosii
y- bile albe
z-bile negre
x+y+z=624
x=5y
z=x+y=5y+y=6y
5y+y+6y=624
12y=624
y=52
x=5y=5.52=260
z=6y=6.52=312
