Chuck spent a total of $38 on a pair of shoes and a new jacket. The shoes cost $6 more than the jacket. Write a system of equations to find the cost of the shoes x and the cost of the jacket y. Then find the cost of the shoes? Select 2 equations and 1 cost.

• 6x + y = 38

• x + y = 38

• y = 6 - x

• y = x - 6

• $22
