Answer:

(d) Using the commutative property

Step-by-step explanation:

Given

The above steps

Required

Which is not part of the process

We have:

[tex]5(2x-8)= 20[/tex]

[tex]10x - 40 = 20[/tex]

[tex]10x - 40+ 40 = 20 + 40[/tex]

[tex]10x = 60[/tex]

[tex]\frac{10x}{10} = \frac{60}{10}[/tex]

[tex]x = 6[/tex]

Comparing the above steps with the given list of options, we can see that the commutative property is not applied at all.

Other properties are:

[tex]5(2x-8)= 20[/tex] ---- Distributive

[tex]10x - 40+ 40 = 20 + 40[/tex] ---- Like terms

[tex]\frac{10x}{10} = \frac{60}{10}[/tex] --- Isolating the variable
