To find the sum of 20k + 5n, you simply combine the like terms.
When combining like terms, you add or subtract the coefficients while keeping the variables unchanged.
Here, 20k and 5n are two different terms. The term 20k has a coefficient of 20 and the variable k. The term 5n has a coefficient of 5 and the variable n.
Since the variables (k and n) are different, we cannot combine them. Therefore, the sum of 20k + 5n cannot be simplified any further.
