Hi,
How can you solve this problem 3x+9=5
The idea is to get x alone <u>on one side </u> of the equal sign...
so one can read  " x = (the answer)"
 3x + 9 = 5
  3x + 9 - 9 =  5 - 9     |removing the 9 from the x side by adding (-9) to both sides
       3x = -4            |removing the 3 from the x side by dividing both sides by 3
        x = <sup>-4</sup>&frasl;<sub>3</sub>
