Adding variables with equations

marty09x (21)
hi, i'm trying to receive this equations in the output with the sum:
The sum of
3a+9b+10c-8d=6
9a-2b+3c-4d=4
12a+7b+13c-12d=10
i would appreciate any suggestions how to correct the syntax errors to compile the program.

    sum = [a],[b],[c],[d],[e];

	cout <<"The sum of "<<endl;

	cout <<[a]<<"a"<<[b]<<"b"<<[c]<<"c"<<[d]<<"d"<<"="<<[e]<< endl; 
 
    return 0; 
}

And the []s in your cout are redundant.

Thank you i rewrote it and got it to compile but realize this was not the instructions given by the professor.

Why have you opened so many topics about the same stuff?

 
 
sum = a + b + c + d + e;

What is sum supposed to be for?
And why don't you just output "12a+7b+13c-12d=10" directly?
What you're trying to do would make sense if the user could specify two arbitrary equations, but that is not the case. The result is already known beforehand and your current code cannot be used in a generic way anyway.
