For this question, we are given a sentence in plain english and we want to translate it into an algebraic equation and then solve the algebraic equation.
00:11
We're using x for a variable.
00:14
So let's figure out what the equation is first by looking at this sentence.
00:19
So since we're using x as our variable, wherever we see a number, we might as well put in x.
00:31
So right here and right here we should be thinking about x.
00:41
Now, looking at the rest of this sentence, we've got the sum of four times a number and seven.
00:48
So four times a number is 4x, and the sum of four times a number and seven, well, that would mean 4x plus seven, is, we can just, substitute and equals 10 more than the number.
01:08
Well, the number is again x and we want 10 more than that...
