17 solve 3x + 11= k for x a. x= k-11 divided by 3 b. x= k - 11 c. x= 3k - 11 d. x= k+11 divided by 3

The correct answer is:  [A]:  " x = k − 11 divided by 3 " . 

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" .

If you make you answer for clear i can answer it : )
