Question

Produsul a doua numere este 152. Daca se mareste primul numar cu 6,produsul devine 200. Aflati cele doua numere.

Answer 1

axb=152
(a+6)xb=200
axb+6xb=200
152+6xb=200
6xb=200-152
6xb=48
b=48:6
b=8
(a+6)x8=200
a+6=200:8
a+6=25
a=25-6
a=19
proba:19x8=152
            (19+6)x8=25x8=200

Answer 2

a×b=152
(a+6)×b=200
a×b+6×b=200
152 +6×b=200
6×b=200-152
6×b=48→b=48:6=8→b=8
(a+6)×8=200
(a+6)=200:8
a+6=25
a=25-6→a=19
proba:19×8=152
(19+6)×8=25×8=200
