So in this problem, we're told that if one is subtracted from a number, and then this difference is tripled, the result is going to be 11 more than the number.
00:08
So the best way to try and come up with this is let's write the equation where x represents the number that we're looking for.
00:15
So first off, it says that one is getting subtracted from a number, meaning we would take the number, which we're calling x, and we've subtract one away from it.
00:25
Then this difference, meaning this subtraction problem, is getting tripled, meaning this whole thing would get multiplied.
00:31
By 3.
00:32
Well, now we're told the result is, meaning the value of this would equal to, well, it's equal to 11 more than the number, meaning if i take the number and add 11 to it.
00:44
So now, in order to find the number, we just have to solve this equation.
00:47
So first, i'll distribute the 3...
