First you would simplify the left side to get,
ln( ( 3x+1 ) / ( 5+x ) ) = ln 2
Then raise both sides as the power of e, so it would basically cancel out the ln's.
3x+1 / 5+x = 2
3x+1 = 2( 5+x )
3x+1 = 10+2x
x = 9
The problem is already in terms of c.
ax+bx/3=c
ax+bx=3c
x(a+b)=3c
a+b=3c/x
a=3c/x +b or b=3c/x -a

<h2><u>Solution</u> :-</h2>
Given : One carton of eggs contains 12 eggs.
By unitary method we can find the number of eggs in following cartoons :
1 cartoon = 12 eggs
5 cartoons = 12 × 5 = 60 eggs
6 cartoons = 12 × 6 = 72 eggs
7 cartoons = 12 × 7 = 84 eggs
8 cartoons = 12 × 8 = 96 eggs
