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" .
