Question

1/3(3x+12) =4x-5
therefore x=?​

Answer 1

Step-by-step explanation:

$\frac{1}{3} (3x+12) = 4x - 5$  

       $x + 4 = 4x-5$           (contributive property, 1/3 · 3x and 1/3 · 12)

 $x + 4 -4=4x-5-4$     (subtract 4 to both sides)

             $x=4x-9$           (simplify)

     $x-4x=4x-9-4x$   (subtract 4x to both sides)

         $-3x=-9$                (simplify)

          $\frac{-3x}{-3} = \frac{-9}{-3}$                (divide -3 to both sides and apply fraction rule)

             $x = 3$                  

Answer:

x = 3
