Let the number of 10-inch stones be x.
Let the number of 5-inch stones be y.

The total width is 190 inches.
That means that when he adds the combined width of the 10-in. stones and the combined width of the 5-in. stones, they will add up to 190 in.

What is the width of x number of 10-in. stones?
What is the width of y number of 5-in. stones?
