Answer 1

X = -5.

You need the numerator to equal 0 in order for the expression to equal 0. So set the top equal to 0 and solve. 

Answer 2

Answer:

Value of x is -5

Step-by-step explanation:

Given Rational Expression , $\frac{3x+15}{6-x}$

To find: Value of x when Given rational expression equal to 0.

Consider,

$\frac{3x+15}{6-x}=0$

$3x+15=0\times(6-x)$

$3x+15=0$

$3x=0-15$

$3x=-15$

$x=\frac{-15}{3}$

$x=-5$

Therefore, Value of x is -5
