Okay, so we need to find the solution for this equation.
00:04
There is a variable here.
00:08
So i need to use inverse operations to undo all the operations that are happening around the x term and to the x itself so that i can identify the answer.
00:22
Before i start, i'm just going to look at what i think the answer might be.
00:28
My guess is the answer is going to be two.
00:31
Because if i multiply 7 times 2, that would be 14, 14 takeaway 11 is 3.
00:37
So through these inverse operations, i should be basically doing the opposite of what i just did, which is i started by multiplying, then subtracting, which means i need to undo the subtraction first.
00:50
I'm going to add 11 to the negative 11.
00:54
If i do something to one side of the equation, i need to do it to the other side, and so i'm going to add 11 to the right side as well.
01:02
3 plus 11 is the 14 that i mentioned in my guess.
01:07
Negative 11 plus 11...
