HELPPPP

this should be so simple, i need to solve for x given the constants a, b, c, d, e

i keep getting tthe following errors:

Error: File: x.m Line: 1 Column: 10

Invalid expression. Check for missing or extra characters.

Error in untitled2 (line 11)

solve (a == b * ( (1 + (c*x)) / d)^ (d/x) + ( e + e ((1 + ((c*x)/d)^d/x))/((c*x)/d)), x)

a = input('Please enter a: \n');

b = input('Please enter b: \n');

c = input('Please enter c: \n');

d = input('Please enter d: \n');

e = input('Please enter e: \n');

solve (a == b * ( (1 + (c*x)) / d)^ (d/x) + ( e + e ((1 + ((c*x)/d)^d/x))/((c*x)/d)), x)
