u have aloft of questions but I can try to heap u
I'd suggest you begin by subtracting 4 / (x-4) from both sides. Doing that would leave you with 1 / (x-4) - 2 / (x+2) = 0.
LCD is (x-4)(x+2). Mult. all three terms by (x-4)(x+2). The resulting equation is
x+2 - 2(x-4) = 0. Then x+2 = 2x - 8 => x = 10
Subst. 10 for x in the original equation to verify that 10 is indeed a solution.
I believe you haven't included the system of equations for us to solve.
However, I will tell you that you need to solve for one variable in an equation and substitute that into the other equation.
For example:
x = yz; z = x/y
a = zb; a = (x/y)b
Hope this helps!
Answer: The function c(p) represents the cost for (P) people to attend the movies.

Step-by-step explanation:
Answer:
2x + 9 - 5y
Step-by-step explanation:
Collect like terms:
(-2x + 3x + x) + (4 + 5) - 5y
Then, simplify:
2x + 9 - 5y
