Answer:

[tex]20z−8=4(5z-2)[/tex]

Step-by-step explanation:

[tex]20z−8[/tex]

20z can be written as 5 times 2 times 2 times z

8 can be written as 2 times 2 times 2

[tex]20z-8= 5 \cdot 2 \cdot 2 \cdot z- 2 \cdot 2 \cdot 2[/tex]

Greatest common factor for 20z  and 8 is 2 times 2 = 4

Now take out 4 in common

[tex]20z−8=4(5z-2)[/tex]
