2)5y – 3x – 4 – 5x – 3y + 7
3)5x² – 9xy – 4y² – -x² – 6xy + 3y ²
tolong di jawab ya… ini tentang aljabar
1)5x – 9 – 7x + 15y
Jawaban Terkonfirmasi
1) 5x – 9 – 7x + 15y
= 5x – 7x + 15y – 9
= -2x + 15y – 9
2) 5y – 3x – 4 – 5x – 3y + 7
= -3x – 5x + 5y – 3y – 4 + 7
= -8x + 2y + 3
3) 5x² – 9xy – 4y² – -x² – 6xy + 3y²
= 5x² + x² – 4y² + 3y² – 9xy – 6xy
= 6x² – y² – 15xy
Jawabannnya
no.
1. = 5x-7x +15y-9
= -2x+15y-9
2. = -3x-5x5y-3y-4+7
= -8x+2y+3
3. = 5x^2+x^2-4y^2+3y^2-9xy-6xy
= 6x^2-y^2-15xy
