Question 375927: I need to find a solution (x,y) for the following set of numbers....
y=logbase2(x+1)
y=5-logbase2(x-3)
I dont know how to solve this one....

Since they both equal y:



x+1 = 32/(x-3)


(x-7)*(x+5) = 0
x = -5 Discard, since it gives the log of a negative number
x = 7
-------

y = 3
-----
(x,y) = (7,3)
