What is the solutions to the equation w/2w-3=4/w
labwork [276]

Answer:

{2, 6}

Step-by-step explanation:

w/2w-3=4/w  is ambiguous.  Did you mean

   w            4

---------- = ------     ?  If so, please enclose "2w - 3" inside parentheses.

2w - 3       w

Cross multiplying, we get w² = 8w - 12.

Putting this into standard form, we get:

w² - 8w + 12 = 0, which factors into (w - 2)(w - 6) = 0.

The solutions are found by setting each factor = 0 separately and solving the resulting equations for w:  {2, 6}.
