To make y a function x, simply get the y to equal the rest of the values. eg. y=3x+1
You would set the equation equal to 0 and then solve for x. You may get one or several answers for x, x being the number(s) that make the equation equal 0.
x / (x+1) is an already simplified term. In order to "solve" it, you must either know the value of x, or set the entire term equal to some number.
x+y=5
This is not possible to "solve" as such. 3x + 4x = 7x, which is the same as 7x=7x. Clearly, you end up with x=x, which is true, but not useful.This suggests that you have used the wrong method when trying to solve the problem, however your algebra was correct, since x does indeed equal x; it's when you end up with something like 2=1, or 1=0, that you have to worry.
Set each factor, in turn, equal to zero and solve for x.
It is NOT equal. Try calculating tan x, and tan 6x, for a few values of "x", on your scientific calculator. Perhaps you are supposed to solve an equation, and see FOR WHAT values of "x" the two are equal?
To make y a function x, simply get the y to equal the rest of the values. eg. y=3x+1
To find the x or x's values
You cannot solve log x- 2 unless (i) log x - 2 is equal to some number or (ii) x is equal to some number.

Set it equal to 0 and subtract x and solve for y

x+y=5
Add the constants to one side and the x values to the other. You should end up with 8x=16 in which x would equal 2.
