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

Value of x is -5

Explanation:

Given Rational Expression ,
`(3x+15)/(6-x)`

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

Consider,

`(3x+15)/(6-x)=0`

`3x+15=0*(6-x)`

`3x+15=0`

`3x=0-15`

`3x=-15`

`x=(-15)/(3)`

`x=-5`

Therefore, Value of x is -5
