The question contains an expression but no equation (or inequality). An expression cannot have an answer.
It is an expression that can be simplified to: 76p-5
5p x 2p = 10p, then 10p / 4p = 2 remainder 2
11-3p
4p + 9 - 7p + 2 4p - 7p + 9 + 2 p(4 - 7) + 9 + 2 -3p + 11
20p that is wrong because it is not an expression

The question contains an expression but no equation (or inequality). An expression cannot have an answer.
It is an expression that can be simplified to: 76p-5
5p x 2p = 10p, then 10p / 4p = 2 remainder 2
11-3p
4p + 9 - 7p + 2 4p - 7p + 9 + 2 p(4 - 7) + 9 + 2 -3p + 11
The mathematical expression for the 2p radial wave function in quantum mechanics is given by R2p(r) (1/(326))(2r/3a0)e(-r/3a0), where a0 is the Bohr radius.
11p+11
Collect like terms together: 4p + 9 + 7p + 2 = (4p + 7p) + (9 + 2) = (4 + 7)p + 11 = 11p + 11 = 11(p + 1)
There is no equation (nor inequality in the question and so there is nothing to solve.The expression can be simplified to 4p - 16 which can be factorised to 4*(p - 4). That is as far as you can go.
34 is an equivalent expression.
