Distributive property is used to multiply a single term by two or more terms inside a set of parenthesis. Multiply the outside term (5) by 7 first.

Then multiply the outside term (5) by 9.

Combine the two remaining terms by keeping the sign that was originally inside the parenthesis.

We need to distribute -3 by multiplying both terms inside the parentheses by -3.:

 .

Now we can multiply and simplify. Remember that multiplying two negative numbers results in a positive number:

Remember that a negative multiplied by a negative is positive, and a negative multiplied by a positive is negative.

Distribute the  through the parentheses by multiplying it by each of the two terms: 

First, we must use the distributive property on both sides of the equation.

The distributive property states:

Therefore:

Now, we can solve the expression like a two-step equation with variables on both sides. Do not forget the properties of equality and perform the same operations on both sides.

Subtract  from both sides.

Simplify.

Now, the problem is a one-step equation.

Add  to both sides.

Solve.

Check the answer by substituting it back into the original equation. Both sides should equal to each other.

First, we must use the distributive property on both sides of the equation.

The distributive property states:

In other words, we can take the factor on the outside of the parentheses and multiply it by each term inside the parentheses.  

Therefore:

Simplify.

To solve this problem we need to use the distributive property. This property is used to multiply a term outside of a set of parentheses by each of the terms in the parentheses. 

Now we have 

This expression is simplified because we cannot add  to  because  has a variable  attached to it. 

To solve this problem we need to use the distributive property. This property is used to multiply a term outside of a set of parentheses by each of the terms in the parentheses. 

Now we have 

This expression is simplified because we cannot add  to  because  has a variable  attached to it. 

To solve this problem we need to use the distributive property. This property is used to multiply a term outside of a set of parentheses by each of the terms in the parentheses. 

Now we have 

This expression is simplified because we cannot add  to  because  has a variable  attached to it. 

To solve this problem we need to use the distributive property. This property is used to multiply a term outside of a set of parentheses by each of the terms in the parentheses. 

Now we have 

This expression is simplified because we cannot add  to  because we cannot add a number to a variable. 

To solve this problem we need to use the distributive property. This property is used to multiply a term outside of a set of parentheses by each of the terms in the parentheses. 

Now we have 

This expression is simplified because we cannot add  to  because  has a variable  attached to it.
