So, you would multiply 6.93 and 4.21, and then add 3.56, which gives you 32.7353. You would then add 4.21 to that, which gives you 36.945. Now, you have this:
36.945/x = 6.93
You would then divide 6.93 by 36.945.
36.945/6.93=5.33116883117
You would round that number to the nearest hundredth place, which would be 5.33.
Plug that into the equation and you get:
6.93151969981
You round that to the nearest hundredth, and you get 6.93.
