Question

Solve the following system of equations by using the substitution method: t = 4-2s, (1) and t + 2s = 6, (2)

Answer 1

ha ha

Answer 2

what do the (1) and the (2) stand for? t?? or s??

Answer 3

I am not sure if those commas are supposed to be there or not. The instructor put a comma before the (1) on the first equation, but he didn't on the second equation.

Answer 4

Is your instructor Bon Jovi?

Answer 5

LOL, no why?

Answer 6

I'm assuming that the (1) is going to take the place of the "s", and not the "t". but really, it's not specified...

Answer 7

The exact way he worded it was t = 4 - 2s, (1) and for the second equation he put t + 2s = 6 (2)

Answer 8

Does it say to solve for t? or for s....

Answer 9

So I think there is either an omission or a typo in there someplace.

Answer 10

Yes, solve using the substitution method.

Answer 11

he doesn't say whether to solve for t or s.

Answer 12

But we have to solve for either T.... Or we have to solve for S

Answer 13

then he is a silly goose.

Answer 14

Well, he does a lot of copying and pasting his questions, so he may have just not worded it correctly.

Answer 15

here...

Answer 16

t = 4 - 2(s) , (1)

put the one in for s..."substitute"

and get

t = 4 - 2(1)

Answer 17

2*1 = 2 so its now..... t = 4-2 = 2

Answer 18

t=2 for the first...

Answer 19

second one...

Answer 20

t + 2s = 6 , (2)

Answer 21

t + 2(2) = 6..........t + 4 = 6...........t = 2 (after subtracting 4 from both sides

Answer 22

So basically both equations have the same answer?

Answer 23

yea...

Answer 24

okay, I will post this to his question and ask him if he is sure he asked it correctly. LOL thank you Ryan.

Answer 25

they only have the same answer because there were different values for s that we put in namely 1, and 2.. they aren't the same equation though... later

Answer 26

right. thank you.

Answer 27

heyy!
