(E) -3, 5

Explanation:

Given:

equation:

$x - \frac{15}{x} = 2$

Solving this equation further

$x^2 - 15 = 2x\\\\x^2 - 2x - 15 = 0\\\\x^2 +3x - 5x - 15 = 0\\\\x(x+3) -5 (x+3)=0\\\\(x-5)(x+3) = 0\\\\(x-5) = 0, (x+3) = 0\\\\x = -3, 5$

Therefore, the value of x is -3, 5

14=-(p-8) how do i find p

Xelga [282]

Answer:

p=-6

Step-by-step explanation:

14 = -(p-8) (distribute negative into parentheses)

14 = p(-1) -8(-1)

14 = -p + 8 (subtract 8 from both sides)

14 - 8 = -p

6 = -p (multiply both sides by -1 and rearrange)

p = 6(-1) = -6
