(7+x)+x=15
I did trial and error to get x=4.
Where’s the question dude?
The general solution of tan(b·x) = 2, given that the smallest positive solution is x = 0.3, is presented as follows;

The given smallest positive solution of tan (b·x) = 2 is x = 0.3
The general solution of tan (b·x + c) = m, is given as follows;

α = arctan(m) = x₀
The minimum positive value of the general solution is therefore presented as follows;


In the given function, tan (b·x), we therefore, have;
c = 0, m = 2, 
The general solution of tan(b·x) = 2, is therefore;
