Question

Gasiti numerele naturale "m"si"n"care verifica egalitatea: (m+5)×(n-5)=24

Answer 1

(m + 5) ×( n- 4) = 24 = 8 × 3
m+5 = 8
m = 8-5
m = 3

n-4 = 3
n = 3+4
n = 7

(m+5) × (n-5) = 24 = 6 × 4
m+5 = 6
m = 6-5
m = 1

n-5 = 4
n = 4+5
n = 9


(m+5) × (n-5) = 24 = 12 × 2
m+5 = 12
m = 12-5
m = 7

n-5 = 2
n =2+5
n = 7

(m ; n) = (3 ; 7); (1 ; 9) ; (7; 7) .
