Question

Evaluate 3 - 9 when z = = 24

Answer 1

$\frac{x}{4}-9$

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

$\frac{24}{4}-9$

Now let us find the value of 24/4

$\frac{24}{4}=6$

$\frac{x}{4}-9=6-9$

Now subtract 9 from 6

$6-9=-3$

Then

$\frac{x}{4}-9=\frac{24}{4}-9=6-9=-3$

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