Question

-4( 6 ) = \frac{4z - 9}{6}( 6 )
= 4z - 9

Explanation:

Step1: Simplify left side

Multiply -4 and 6.
$-4\times6 = -24$

Step2: Simplify right side

The 6 in the numerator and denominator of the fraction $\frac{4z - 9}{6}$ will cancel out when multiplied by 6, leaving $4z - 9$. And we already found the left side is -24. So the left side simplifies to -24.

Answer:

-24
