Jawaban:
a. 5r - 3p + 8s
b. 20a + 6b - 5c + 12
c. 15x + 13z
Penjelasan dengan langkah-langkah:
a. (4r + p + 3s) + (r - 4p + 5s) =
(4r + r) + (p - 4p) + (3s + 5s) =
5r + (-3p) + 8s = 5r - 3p + 8s
b. (11a - b - 5c + 4) + (9a + 7b + 8) =
(11a + 9a) + (- b + 7b) - 5c + (4+8) =
20a + 6b - 5c + 12
c. (8x - 7y + 6z) + (7x + 7y + 7z) =
(8x + 7x) + (-7y + 7y) + (6z + 7z) =
15x + 0 + 13z = 15x + 13z
2. a. 4r + p + 3s + r - 4p + 5s
= 4r + r + p - 4p + 3s + 5s
= 5r - 3p + 8s

b. 11a - b - 5c + 4 + 9a + 7b + 8
= 11a + 9a - b + 7b - 5c + 4 + 8
= 20a + 6b - 5c + 12

c. 8x - 7y + 6z + 7x + 7y + 7z
= 8x + 7x - 7y + 7y + 6z + 7z
= 15x + 13z
