5s + 10t = 3
2s + 1t = 0

Any help is appreciated!:confused:

from your second equation, t = -2s

put this into your first one and then solve for s. use your value for s to find t.

let me know how you get on!

5s + 10t = 3
2s + 1t = 0

Any help is appreciated!:confused:
I did the problem and came up with S= -1/5.. What did I do wrong?

Why can't s be -1/5?

What do you get for t?

s = -1/5 looks right to me
Now work out t.

5s + 10t = 3
2s + 1t = 0

Any help is appreciated!:confused:
So if S= -1/5 and t =-2s, you have to still solve for the t
I got t = 2/3
Is this correct?

s = -1/5 is correct! If your book says a different answer than the book is incorrect. Answers books have mistakes in them at times and I talk from experience.
Anyhow plugging in s = -1/5 into one of your equations should get you t = 2/5

I assume you typed 2/3 wrong, everything else you said is correct
