30x-11= 30/x

30x-11= 30/x

Answer 1

[Ameer Hamza]

If you want to solve this equation for x, then you have the following two methods to do it in MATLAB.

1) If you have symbolic toolbox

syms x

eq = 30*x-11 == 30/x;
sol = solve(eq);

2) Your equation is a polynomial (for ). You can use roots()

% polynomial is 30x^2-11x-30=0
cf = [30 -11 -30];
sol = roots(cf);

Answer 2

[Stephen23]

Simple numeric solution:

>> fun = @(x) 30*x - 11 - 30./x;
>> x = fzero(fun,pi)
x =
    1.2000

Checking:

>> 30*x-11
ans =
    25
>> 30/x
ans =
    25
