I assume you mean 3x - 3 = 10 In algebra there is no "correct" first step to solving for x as long as you follow math rules, however the easiest first step is to add 3 to both sides (REMEMBER THAT WHATEVER YOU DO ON ONE SIDE OF THE EQUATION YOU HAVE TO DO TO THE OTHER) Therefore: 3x - 3 = 10 3x - 3 + 3 = 10 + 3 3x = 13 Notice that when we do this we have fewer terms to deal with on the left hand side. See if you can finish it off.
You can find the algorithms and an easy step-by-step guide at rubiks.com. Go to the academy link on the homepage and then once there, the first one of the links to the special pages should be the 3X3 solution. Obvously, go to that.
it is 3x3 not that hard
Erik Akkersdijk holds the record for the 3x3 Rubik's cube, solving it in 7.08 seconds. Kowalski
y
In the case of 27, there is only one possible factor tree - using the factors 3 and 9 as the first step. 27 3 x 9 3 x (3x3)
3x3
no 3x3 is 9 3x4 is 12
Multiple them! 3x3=9 squares!
-31-8x if the first and second x is a multiplication sign.
(3x3x3 - 3x3)/(3 - 3x3) = (27-9)/(3-9) = 18/(-6) = -3 if you mean: 3x3x3 - (3x3)/(3 - 3x3) = 27 - 9/(-6) = 28 1/2
the area of 3x3 meters is 9 meters
17 2x4=8+(3x3)=17 3x3=9 9+8=17
