It's driving me nuts!!! I received this equation in an Elementary Algebra problem set, and was not given any good instructions on how to solve when there is a "t" on each side with another variable by them. HELP!!!
Solve: P + rt = bt + 2 (for "t")

P + rt = bt + 2
P + rt - bt = 2
(r - b)t = 2 - P
t = (2 - P)/(r - b)

I'm not too sure what your question is asking, but I'm assuming that P, r and b are integers while t is your variable.
To solve for t, make sure that all terms containing t are on one side of the equation, while all other terms are on the other side.
P + rt = bt + 2
rt - bt = 2 - P
Factorise t on the left hand side of the equation, since it is common to both rt and bt.
t (r - b) = 2 - P
Finally, divide the right hand side of the equation by (r - b).
t = (2 - P) / (r - b)
Hope that answered your question!

P+rt=bt+2 solve for "t"
P-2+rt=bt+2-2
P-2+rt=bt
P-2+rt-rt=bt-rt
P-2=t(b-r)/b-r
P-2/b-r=t
answer P-2/b-r= t

P + rt = bt + 2 first you move bt to the left side (becomes -bt)
and move P to rite side (becomes -P)
rt-bt=2-P group t up
t*(r-b) = 2-P
t = (2-P)/(r-b)
hope this help

Move the t's to the same side:
rt - bt = 2 - P
Isolate t on the left:
t*(r-b) = 2 - P
Divide by (r-b) on both sides:
(t*(r-b)) / (r-b) = (2 - P) / (r-b)
Yielding:
t = (2-P) / (r-b)

Solve for "t" means to express t in terms of r, b and P.
P + rt = bt + 2
P-2 = bt-rt
P-2 = t(b-r)
(P-2)/(b-r) = t

Remember, your goal is always to isolate t. In this case, we isolate the terms with t by:
rt-bt= 2 - P
Now that we have the t terms isolated, factor out the t.
t(r-b) = 2 - P
And divide for the solution:
t = (2-P)/(r-b)

P + rt = bt + 2
rt-bt= 2-P
t(r-b) = 2-P
t = (2-P) / (r-b)
is the only solution i can give.

given: p + rt = bt + 2
find: t
solution:
rt - bt = 2-p
t(r-b) = 2-p
t = (2-p)/(r-b)
therefore: t = (2-p)/(r-b)

P + rt = bt + 2
bt-rt = P-2
t(b-r) = P-2
t = (P-2)/(b-r)
