Question

What are the values of x

Answer 1

x=17

Explanation:

Answer 2

x=5 x=-3

Explanation:

x - 15/x = 2

Multiply each term by x to get rid of the fraction

x(x - 15/x) = 2*x

x^2 -15 = 2x

Subtract 2x from each side

x^2 -2x -15 = 2x-2x

x^2 -2x-15 = 0

Factor the left hand side

(x-5) (x+3) =0

Using the zero product property

x-5=0 x+3 =0

x=5 x=-3
