The correct answer is: [A]: " x = k − 11 divided by 3 " .
_____________________________________________________
Step-by-step explanation:
_____________________________________________________
Given: " 3x + 11 = k " ; Solve for "x" ;
_____________________________________________________
3x + 11 = k ;

Subtract "11" from each side of the equation;

3x + 11 − 11 = k − 11 ;

to get:

3x = k − 11 ;

Now, divide EACH SIDE of the equation by "3" ; to isolate "x" on one side of the equation; & to solve for "x" ;

3x / 3 = (
k − 11) / 3 ;

to get:
______________________________________________________
x = " (k − 11) / 3 " ;
______________________________________________________
which is: Answer choice: [A]: " x = k − 11 divided by 3" .
