Hi everyone!

I'm currently working on a problem, but I'll simplify it so that everyone can know what I mean.

This is the file:
----------------------------------------------------------------------

close all
clear all
clc

syms x

a=5;
b=7;
c=a+b;

solve('x/2*a-7*b-13*c+14*a*b*x*c-34*x-7*b')
----------------------------------------------------------------------

Result:

ans =

(28*b + 26*c)/(a + 28*a*b*c - 68)

How can I get the value of "x" in a normal number, not symbolic expression?

Also

If I use:

eval('x/2*a-7*b-13*c+14*a*b*x*c-34*x-7*b')

I get this:

ans =

(11697*x)/2 - 254


All I need is to get the value of x....

Thanks in Advance!
 

hi
this code solves the equation x/2*a-7*b-13*c+14*a*b*x*c-34*x-7*b and get answer:
% ---------------------------------------------------------------------------
syms x
result=solve('x/2*a-7*b-13*c+14*a*b*x*c-34*x-7*b');
a=5;
b=7;
c=a+b;
x=eval(result)
% end-------------------------------------------------------------------
