Okay, so first, let's figure out what variable our number is.
00:04
So we have something called a number.
00:07
This can be any variable, so to just make it easy, let's just call this number x.
00:13
So just reading the sentence, we're going to write down our equation from left to right.
00:18
So four times a number, so four times x, minus, that's just subtraction, the symbol minus, minus six is equal to well, what symbol is equal to? just equals.
00:37
The sum, so there's going to be two things that are added.
00:43
Sum means addition.
00:46
The sum of three times a number.
00:50
So three times the number x and two.
00:56
So i'm adding 3x and 2.
00:58
Okay.
01:00
So let's rewind that.
01:02
So four times a number minus six is equal to the sum.
01:06
So the operation between these two is adding a three times the number into.
01:10
Okay, so now let's just figure out what that number is.
01:14
So my goal is to get x completely by itself...
