How to solve $3x+\sin x = e^x$ How doese one solve this equation?
$$
3x+\sin x = e^x
$$
I tried graphing it and could only find approximate solutions, not the exact solutions.
My friends said to use Newton-Raphson, Lagrange interpolation, etc., but I don't know what these are as they are much beyond the high school syllabus. 

sorry
f(b)=3(1)+sin(1)−e1= is Not Equal to ---> 1.12...
f(b)=3(1)+sin(1)−e1= is Equal to  ----> 0.299170578
And
f(0.5)=3(0.5)+sin(0.5)−e0.5= is Not Equal to ---> 0.33...>0
f(0.5)=3(0.5)+sin(0.5)−e0.5= is Equal to  ---->   -0.1399947352
