Let's start with an
easy one:
| Solve
|
 |
We can just look at it
and see that
x =
10...
But, what if we didn't
see that? What would we do?
Here's the Algebra
trick:
We'll
add 3 to both
sides!
*Remember the see saw?
Whatever we do to one side of the equation,
we have to
do to the other side.
Why did we
ADD 3?
To undo this!
+ is the opposite of
-
The goal is to get the
x alone. Just imagine that
Mr. X hasn't showered
in a few weeks and everyone wants to get away from him.
It's your job to help.
