10p+6q-5p-8q =
10p+6q-5p-8q =
10p - 5p + 6q - 8q =
5p - 2q =
is it 10
This isn't an equation. Your instructions say to collect like terms. I did.
To collect like terms, you need to combine the terms that have the same variable and exponent. In this expression, you have two variables, p and q.
The terms with the variable p are:
10p and -5p
The terms with the variable q are:
6q and -8q
To collect the like terms, you will add the coefficients (numbers in front) of the same variables. Let's combine the like terms for p first:
10p - 5p = (10 - 5)p = 5p
Now, let's combine the like terms for q:
6q - 8q = (6 - 8)q = -2q
Therefore, the expression 10p + 6q - 5p - 8q simplifies to:
5p - 2q
