Question

how do i do this?
W=T(s1-s2)-Q solve for s2

Answer 1

Answer 2

Distribute the T first to simplify.

Answer 3

Then move every term that does not have s2 in it to the other side with the W, then you'll see what the last step is.

Answer 4

okay

Answer 5

is the finl nswer W-s1-Q=s2

Answer 6

What happened to T?

Answer 7

and Q will be positive when moved to the side with the W.
Remember that when transposing terms, if you change sides, change signs.

Answer 8

s2=Ts1+Q-W/T

Answer 9

so positive T at the bottom

Answer 10

That's really close, I think you just have opposite signs. I'll work through it again just to be sure.

Answer 11

Actually, I think what you have is correct, but put parentheses around everything you are dividing by T like (Ts1-Q-W)/T, but I think the Q should also be negative.

Answer 12

Here's another method:
\[W=T(s_1-s_2)-Q\]
\[W+Q=T(s_1-s_2)\]
\[(W+Q)/T=s_1-s_2\]
\[s_2=s_1-(W+Q)/T\]
