6x-5y-2z dan -8x+6y+9z​

Jawaban:

Penjumlahan bentuk aljabar :

=(6x – 5y – 2z) + (-8x + 6y + 9z)

= 6x – 5y – 2z – 8x + 6y + 9z

= 6x – 8x – 5y + 6y – 2z + 9z

= -2x + y + 7z

semoga membantu

Jawaban:

(6x-5y-2z)-(-8x+6y+9z)

(6x+5y+2z)-(8x-6y-9z)

= 6x-8x+5y-5y+9z-2z

=-2x+y+7z

maaf kalo salah
