While adding such algebraic expressions, we combine the like terms which contains the same variables infact same degree of variables.
Given expression:
Here 12p and 3p are like terms because they are having same variable that is p. So, we can compute any operation like hear it's subtraction.
➝ 8r + (12p - 3p)
➝ 8r + 9p
Now no more like terms are there, So the final answer is 8r + 9p. And we are done!
