Buat yang bisa aljabar. Tolong ya dijawab dengan benar. 1. 8x + 3y- 2x+5y = 2. 2m-3n+4k+6m+7n-k = 3. 10x- 2xy + 8xy2 + 6xy-3x+5xy2 = 4. 3x-8y+6z -10x-2y-15z = T

1. 8x + 3y- 2x+5y
= 8x - 2x + 3y + 5y
= 6x + 8y.

2. 2m-3n+4k+6m+7n-k
= 2m + 6m - 3n + 7n + 4k - k
= 8m + 4n + 3k.

3. 10x- 2xy + 8xy2 + 6xy-3x+5xy2
= 10x - 3x - 2xy + 6xy + 8xy2 + 5xy2
= 7x + 4xy + 13xy2.

4. 3x-8y+6z -10x-2y-15z
= 3x - 10x - 8y - 2y + 6z - 15z
= - 7x - 10y - 9z.

1. 8x + 3y - 2x + 5y = 6x + 8y
2. 2m - 3n + 4k + 6m + 7n - k = 8m + 4n + 3k
3. 10x - 2xy + 8xy2 + 6xy - 3x + 5xy2 = 13xy2 + 4xy + 7x
4. 3x-8y+6z-10x-2y-15z = - 7x - 10y - 9z
