Answer 1

→ 5y + 2x - 5n + 2z + 4y - 5z + 2n

→ 2x + 5y + 4y + 2z - 5z - 5n + 2n

→ 2x + (5 + 4)y + (2 - 5)z + (-5 + 2)n

→ 2x + 9y + (-3z) + (-3n)

→ 2x + 9y - 3z - 3n

_________

Jawaban:

Hasil dari 5y + 2x - 5n + 2z + 4y - 5z + 2n adalah 2x + 9y - 3n - 3z

Penjelasan dengan langkah-langkah:

= 5y + 2x - 5n + 2z + 4y - 5z + 2n

= 5y + 2x + ( - 5n ) + 2z + 4y + ( - 5z ) + 2n

= (5y + 4y) + 2x + 2n + ( - 5n ) + 2z + ( - 5z )

= 9y + 2x + (2n + ( - 5n )) + (2z + ( - 5z ))

= 2x + 9y + ( - 3n ) + ( - 3z )

= 2x + 9y - 3n - 3z
