Question

480/x-480/x+8=3 what is the solution ​

Answer 1

Answer:

Step-by-step explanation:

Answers are  x = 40 or -32.

480/(x-8)  -  480/x  =   3      To solve for x.

       480*[x - (x-8)] / [(x-8)x ] = 3

        3x(x-8) = 8*480

         x² - 8 x - 1280 = 0      :             - 1280 = - 40 * 32

        x² -40 x + 32 x - 1280 = 0

         (x - 40)x + 32 (x-40) = 0

           x = 40   or  x = -32

That is the answer....
