Wk10Day5 TUTORIAL 1-Step Mult/Div. Eqtns (with Negs)
Hey there! We're Pokemon and we're going to help you solve 1-Step Equations (specifically, multiplying/div) First thing to know: YOU GET TO USE THE CALCULATOR ONTHIS ASSIGNMENT!! This is the first time ever. Go to yourteacher's page and find the Desmos calculator now!
SQUIRTLE SAYS: Remember to use your triangle for multiplying a pos (+) and negs (-). You get to to use yourcalculator, but if you accidentally mess up, you willrealize it and save yourself!  The triangle reminds me of how Water Pokemon weaken Fire Pokemon, but Grass Pokemon weaken Water Pokemon!

CHARMANDER SAYS: A number next to a letter (variable), 
with nothing in between, means to MULTIPLY. A number that
 looks like a FRACTION is really DIVIDING. 

HOWEVER, we often want to get RID of the number next
to the letter (variable). 
3x  ↔

x
3 • x (3 times x)
?
x÷3 (div-ided by 3)
?
BULBASAUR SAYS: We do the INVERSEoperation to BOTH SIDES to get the letter(variable) alone. On the side w/the letterthe numbers will CANCEL out to make 1.On the side w/the number, we will get thereal answer. Look at the examples below!
