Question

15x=75Write which property of equality you used.

Answer 1

1) Given this equality,

15x = 75 Divide both sides by 15

x=5

2) Then we can write that since x = 5 and 15x = 75 we have here is the Division Property of Equality.

Because in this case, we divided both sides by 15, which is different from zero to find equivalent equality.

3) So
