5÷x-4 - 2÷x+2 = 4÷x-4

1 answer:

8 0

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.

Answer:

96.8 percent

Step-by-step explanation:

You can cut off two zeros from both numbers to compare 1000 to 32.

The difference is 968, and the original is 1000.

So you divide 968 by 1000 to get 0.968 which is equal to 96.8 percent.
