») Convince Me!

What other properties of equality could you apply to

keep the equation 5y = 25 equal? Give an example of

each.

a. Subtraction property

b. Addition property and Multiplication property

Step-by-step explanation:

Given

Solving (a): Which property is applied to

The property applied is the subtraction property of inequality, and it states that:

If

Then

So, in this case:

Solving (b): Other properties

1. The additive property of equality

If

Then

So, the expression can be written as:

When 12 is subtracted from both sides, the equation returns to the original

i.e.

2. The multiplication property of equality

If

Then

So, the expression can be written as:

When both sides are divided by 2, the equation returns to the original

i.e.
