Question

1. (13a - 8b) + (12a + 9b) = 2. (15i + 14b + 13k) + (-30i + 45j + 51k) =
3. Tentukan hasil penjumlahan (3 - 17x + 35z) dan (4x + 23y - 9) =
4. (42n + 35m + 7) - (50m - 20n + 9) =
tolong yahh ,,, semuanya operasi aljabar

Answer 1

1. (13a - 8b) + (12a + 9b) = 25a + b

2. (15i + 14b + 13k) + (-30i + 45j + 51k)
= - 15i + 14b + 45j + 64k

3. (3 - 17x + 35z) + (4x + 23y - 9)
= - 13x + 23y + 35z - 6

4. (42n + 35m + 7) - (50m - 20n + 9)
= 62n - 15m - 2

Answer 2

1. 13a + 12a - 8b + 9b = 25a + b
2. 15i + (-30i) + 14b + 13k + 51k + 45j = -15i +14b + 64k + 45j
3. -17x + 4x + 23y + 35z + 3 + (-9) = -13x + 23y + 35z - 6
4. 42n + 20n + 35m - 50m + 7 - 9 = 62n - 15m - 2
maap kalo salah :D
