We are given the expression 3h+4=P and told to express h in terms of P. This means that we should apply mathematical operations to this equation, so we can "isolate" the variable h on one side of the equality sign. So, at first, we have the given equation
[tex]3h+4=P[/tex]Then, we subtract 4 on both sides, so we get
[tex]3h=P-4[/tex]Finally, we divide both sides by 3, so we get
[tex]h=\frac{P-4}{3}[/tex]
