A basketball coach is ordering jerseys for members of the basketball team and can choose between small, medium, and large jerseys. The cost of a small jersey is x dollars. The cost of a medium jersey is 1 dollar more than the small jersey, and the cost of a large jersey is 2 dollars more than the medium jersey. The coach orders 5 medium jerseys and 7 large jerseys for a total cost of $146. The equation below can be used to find the cost, in dollars, of one small jersey.

5(x+1)+7(x+3)=146

Enter the cost, in dollars, of one small jersey.
