Hello!
I am new to Matlab, and I would like to solve an equation:
The code I wrote is:
syms x;
eqn=(sqrt(1+(0.018/x))-sqrt(0.018/x))/(sqrt(1+(0.06/x)-sqrt(0.06/x))==1.12446);
solx=solve(eqn,x);
But when I put the answer back to the equation, it cannot give me the right value.
Can anyone help me with the solution? Thanks a lot!

Be careful with paranthesis as Per said. Below is the right one:
syms x;
eqn=(sqrt(1+(0.018/x))-sqrt(0.018/x))/(sqrt(1+(0.06/x))-sqrt(0.06/x))==1.12446;
solx=vpa(solve(eqn,x),4)
