Answer:

The answer is a=3

Step-by-step explanation:

  ax^2+c=15x, given equation

\Rightarrow ax^2-15x+c=0, write in the standard form

Given sum of roots =5

\Rightarrow -(\frac{-15}{a})=5\\\Rightarrow \frac{15}{a}=5\\\Rightarrow a=\frac{15}{5}=3

( since sum of roots of ax^2+bx+c=0 is -\frac{b}{a} )
