The Multiplicative Property of Equality allows us to multiply both the left and right sides by (1/a). This is the same as dividing both sides by a
Since 1/a ⋅ a ⋅ x = x, the equation becomes:
x = y

Given that:
a ⋅ x = a ⋅ y
not (a = 0)
Prove that:
x = y
The following properties may be helpful:
if a ⋅ x = a ⋅ y, then (1 / a) ⋅ (a ⋅ x) = (1 / a) ⋅ (a ⋅ y)
if not (a = 0), then (1 / a) ⋅ (a ⋅ x) = x
if not (a = 0), then (1 / a) ⋅ (a ⋅ x) = x
if the following are true:
- a = b
- a = c
- b = d
then c = d
Please write your proof in the table below. Each row should contain one claim. The last claim is the statement that you are trying to prove.
