I read that for an ideal gas, the specific enthalpy (h) at constant pressure is equal to the specific internal energy of the gas. How do I proof that?

I know that:

1.) specific enthalpy = specific internal energy + pressure x specific volume

2.) Internal energy at constant pressure = mass of gas x capacity x change in tempt. + (pressure x volume of gas)

3.) pressure x specific volume = gas constant x temperature

How do I obtain specific internal energy? Do I simply divide both sides by (m)?

How do I proceed on after I've obtained specific internal energy?

Where did you read this? It doesn't sound right, as written.
