To Shmoop or not to Shmoop...

00:05

That is not this question. That's not even the section. This is math...

00:08

...come on now. Alright solve this system 4x -3 y equals 12

00:13

X equal three-plus three fourths y

00:17

And here are the potential answers...

00:20

Okay, so what is this question asking?

00:22

Well, it's another substitution problem like Equal

00:25

and Nutrasweet, but this one is a total trick question.

00:29

If we multiply the bottom equation by four...

00:38

...we get 4x equals twelve plus three y.

00:43

Subtract 3y from both sides and uh...look familiar?

00:47

Yeah they are totally the same equation twinsies.

00:50

So what does that mean? Well let's think about it. Whenever asked to find a

00:55

solution of two equations

00:57

we're really trying to find the point of intersection of the two lines

01:00

01:03

if the two given lines are exactly the same which they are in this case

01:08

that means they intersect each other everywhere

01:11

or at all real numbers. So the correct answer is D.

Too bad Mr. Smith would have given us a gold star. Sniff sniff.
