No, it is a binomial. A monomial only has one term. A plus or minus sign creates or separates terms.
If: 2p+5r = q Then: p = (q-5r)/2
It is an expression that can be simplified to: 3p+q
5p-7q
3q + 2p

p=3 !
It is 2p + 3q. This is an expression and so cannot be solved. It cannot be simplified, and without information about the values of p and q, it cannot be evaluated.

-2p-18
Without prior knowledge of the value of q or r, it is impossible to calculate the answer to this equation.
No.
A monomial is one term. There won't be a plus or minus sign.
