The expression "p + 2q" represents the sum of a variable p and twice the value of another variable q. This can also be written as p + 2 * q, where the asterisk denotes multiplication. In algebraic terms, this expression cannot be simplified further unless specific values are assigned to the variables p and q.
-2p squared
The difference of p and q can be written : p - q Twice the difference is therefore 2 x (p - q) which can also be written as 2(p - q) OR 2p - 2q. Consequently you can create another variable (say) y and make this equal to twice the difference of p and q by simply writing, y = 2(p -q)
5p-1=2p-20 3p=21 p=7
P! / q!(p-q)!
If: 2p+5r = q Then: p = (q-5r)/2
p=3 !

p + 22q2
It equals 2p because p+p=2p.
Solving by elimination: p = 3 and q = -2
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.
