Il risultato è **15**.

Solución

La differenza tra il triplo della somma di \( x \) e \( y \) e il doppio della loro differenza può essere espressa matematicamente come: \[ 3(x + y) - 2(x - y) \] Sostituendo i valori \( x = 5 \) e \( y = 2 \): \[ 3(5 + 2) - 2(5 - 2) = 3 \times 7 - 2 \times 3 = 21 - 6 = 15 \] Quindi, il risultato è **15**.

Per calcolare la differenza tra il triplo della somma di \( x \) e \( y \) e il doppio della loro differenza, dobbiamo prima calcolare ciascun componente. La somma di \( x \) e \( y \) è \( 5 + 2 = 7 \), quindi il triplo della somma è \( 3 \times 7 = 21 \). La differenza di \( x \) e \( y \) è \( 5 - 2 = 3 \), quindi il doppio della differenza è \( 2 \times 3 = 6 \). Ora possiamo trovare la differenza richiesta: \( 21 - 6 = 15 \). La risposta finale è \( 15 \).
