Oh Ah long time ago in a system far far

away two lines of intersected form a solution and test

takers everywhere scrambling to determine the coordinates of this intersection

before the evil darth proctor starts tapping his foot Like

all heroes intent on saving the universe from evil we

need a strategy because one equation has already solved for

why use the fur force or write Well because we

didn't exactly pass jed i training Use the substitution method

that plug the y equals x plus five into the

first equation deployed parenthetical shields to keep the quantity x

plus five together as it breaks through the atmosphere into

hostile territory Looks like this three x plus two wise

five and then he got three x plus two times

that quantity X plus five is five Cassie we substituted

the x plus five They're for why they're very clever

Then we just distribute to across the entire quantity of

explosive five before simplifying and if see threepio is really

fluent in six million forms of communication and i'll surely

one of them is algebra right Where's a good droid

when we need one So here's the math three x

plus Two time's going to expose five get five x

plus ten is five No we get five Acts is

minus 5 we take away ten from both sides and

then we just divide by five and we've got x

equals negative one Beware Mind tricks of six lords x

equals negative one is only part of the solution Remember

the hone in on the target we find the x

coordinates of the solution by plugging acts back into either

equation Time is of the essence so use the second

equation it has already solved for why and it's really

easy in short right y equals x plus five just

stick in the negative one right there So why equals

negative one plus five or just five months One So

why is four And in the final episode it is

revealed that the solution is negative one four or a 00:02:01.988 --> [endTime] letter a maybe math force be with you
