Question

Evaluate 3 - 9 when z = = 24

Answer 1

`(x)/(4)-9`

The value of x = 24, then replace x in the expression by 24

`(24)/(4)-9`

Now let us find the value of 24/4

`(24)/(4)=6`

`(x)/(4)-9=6-9`

Now subtract 9 from 6

`6-9=-3`

Then

`(x)/(4)-9=(24)/(4)-9=6-9=-3`

The value of the expression is -3 at x = 24
