Let

${\displaystyle \underset{1}{\overset{4}{}}}f(x)dx=a,{\displaystyle \underset{4}{\overset{7}{}}}f(x)dx=b,{\displaystyle \underset{1}{\overset{3}{}}}g(x)dx=p,{\displaystyle \underset{3}{\overset{7}{}}}g(x)dx=q$

Using properties of the definite integral, evaluate the following definite integral.

${\displaystyle \underset{1}{\overset{7}{}}}(2f(x)-pg(x)+e)dx$

where $a,b,p,$ and $q$ are real numbers and $e$ is the natural number.
