Răspuns :
e = numarul de elevi
p = numarul de pomi
-------
p = e + 25
e = (p / 2) + 4 l inmultim ecuatia cu 2
-------
p - e = 25
2e = p + 8
-------
p - e = 25
2e - p = 8
------------------- adunam cele 2 ecuatii si scapam de p
e = 33 elevi
p = e + 25
p = 33 + 25
p = 58 pomi
p = numarul de pomi

x-nr de elevi
x+25 -nr de pomi
2(x-4) -nr de pomi
x+25=2(x-4)
x+25=2x-8
x-2x= -8-25
-x= -33
x=33 elevi
x+25=33+25= 58 pomi
x+25 -nr de pomi
2(x-4) -nr de pomi
x+25=2(x-4)
x+25=2x-8
x-2x= -8-25
-x= -33
x=33 elevi
x+25=33+25= 58 pomi
