Answer:
Property of equality division
Step-by-step explanation:
Given
c = d
b ≠ 0 then c∕b = d∕b
Required
State the property used
From list of options a through d, only option A best fits the description.
This is so because property of equality division is such that
given two variables c and d where c = d
Provided that b ≠ 0
Take for instance;
b = 2; c = 8 and d = 8;
This implies that
Divide both sides by 2 (assumed value of b)
