Oh no! I have a test on the X variable today! How could I forget?! I can't remember what that is!!
What is X?
Max, I forgot we had that precalc test today, care to remind me how to solve for the x variable?
Of course! Let's think of a simple example. How about this, 2x+1=5.
When did we learn this?
Should I remember this?
PEMDAS is vital - parenthesis, exponents, mult/div, add/sub. We must solve for the x variable according to these orders of operations.
A student named Bridgette is getting on the bus and forgot she had a precalc test on what the x variable is and how to solve it!! How tragic.
Do I remember this?
In 2x+1=5, we want to isolate x. To do this, we subtract 1 from both sides first, this way we get the term with x alone. Now, we have 2x=4. To isolate the x variable, we must divide by 2 on both sides.Now we've go tour answer, the x variable is 2!
Frustrated, Bridgette swallows her pride and asks her good pal Max how to solve for the x variable in an equation. Max, an intellectual, is very happy to spread his knowledge.
Why thank you!
Bridgette appreciates the help Max is providing. However, she remembers nothing that he is saying, and hasn't the slightest clue what PEMDAS is.
Max begins to go through the problem, and at first, Bridgette is still confused. But when it is all explains, she feels fairly confident for her test.
Oh I remember that!
Bridgette and Max are about to take their test. Bridgette is a little nervous, but feels much better now that Max has shown her how to properly solve for the x variable.
Hope I helped! Just remember, to solve for the x variable, you ultimately just want to get x alone!
After the test is done, Bridgette feels super relieved. She feels as though the test was easy, all thanks the help she go from Max. Now, she thinks she can be the teacher.
Wow! I basically am the math teacher now. I thought I'd fail that test, but I think I did great!
