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:

Value of x is -5

Step-by-step explanation:

Given Rational Expression , [tex]\frac{3x+15}{6-x}[/tex]

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

Consider,

[tex]\frac{3x+15}{6-x}=0[/tex]

[tex]3x+15=0\times(6-x)[/tex]

[tex]3x+15=0[/tex]

[tex]3x=0-15[/tex]

[tex]3x=-15[/tex]

[tex]x=\frac{-15}{3}[/tex]

[tex]x=-5[/tex]

Therefore, Value of x is -5
