The properties that can be used to solve 7y - 15 = -29 are

Addition property of equality and inverseproperty of multiplication.

Given equation is 7y - 15 = -29.

We will solve for y and see which of the given following properties are applied.

What is addition property of equality and the inverse property of multiplication?

Addition property of equality

If two expressions are equal to each other, and you add the same value to both sides of the equation, the equation will remain equal.

Inverse property of multiplication

It states that every non-zero x multiplied with 1/x will equal 1.

Solve for y.

7y - 15 = -29

We will add 17 on both sides of the equation.

7y - 15 + 15 = -29 + 15

7y = -14

Now, multiply 1/7 into both sides of the equation.

7y / 7 = -14 / 7

y = -2

While solving for y we see that we have to use the addition property of equality and inverse property of multiplication.
