We can create an equation to help us solve this problem.

Washer + Dryer = 1010

Since the washer cost $60 more than the dryer, we can create another equation.

Washer = 60 + Dryer

Now, let’s use variables instead of the words.

W + D = 1010

W = 60 + D

Let’s create one equation using only one variable. We are using a method called substitution. Do you notice that we can replace W with 60 + D?

W + D = 1010

W = 60 + D

60 + D + D = 1010

Now, this is an equation that we can solve because there is only 1 type of variable. Let’s combine our like-terms.

60 + 2D = 1010

Subtract 60 on both sides.

2D = 950

Divide both sides by 2.

D = 475 So, the dryer costs $475.

Now, go back and make sure we answered the question. Since they wanted the cost of the dryer only, we did! 🙂
