Five multiplied (the difference of a 'number' and 6) is "20";
The "is" refers to an "equal sign";
Let us refer to the unknown number with the variable, "x" ;
Re: The "difference" of a "number and 6" ;
Note the "difference" indicates "subtraction:
So; " (x - 6) ;
"Five times (that difference)" shall be written as:
5*(x - 6) ;
or: 5(x - 6) ;
We are told that this value "is 20" ; that is: "equal to 20" ;
So we can rewite the expression; as follows:
" (5x - 6) = 20 " ;
Which corresponds to:
Answer choice: [C]: " 5(x - 6) = 20 " .
