Multiply both sides of the first equation by

:

This is quadratic in

; to make this clear, substitute

. Then

One of these solutions for

is negative. But, if

is real, then

is always supposed to be positive, so we can throw out the negative root, leaving

.
We actually don't have to solve for

exactly. We can just rewrite the next two equations in terms of

.


Since

, we get

Answer:
2
Step-by-step explanation:
(Pemdas)
1). 3(x+1)
3x + 3
2) 5(x+8)
5x + 40
3) 4(x+6)
4x + 24
1/4 because there is 2 LR ads and 6 other ads, making a total of 8 and 2/8 simplifies to 1/4. Hope this helped!
