Here's an unshmoopy question you just might find on an exam somewhere in life...

00:06

Solve for z, when x = 2 and y = 5. 3x + 4y = z

00:12

And here are the potential answers...

00:17

OK so what is this question asking?

00:18

Well it's really a plug and play deal.

00:21

Just substitute 2 for x and 5 for y and we get to the promised land.

00:28

We have 3x plus 4y, which becomes 3 times 2 plus 4 times 5 or... 6 plus 20...

00:35

...which totals 26.

00:36

E. Done.
