Amanda, placed 2 orders with an Internet clothing store. The first order was for 13 ties, 4 pairs of suspenders, and totaled $487.00, . The second order was 6 ties and 2 pairs of suspenders, and totaled $232.00, . The bill doesn't list the items prices, but all ties have the same price and all suspenders have the same price. What is the cost of 1 tie and of 1 pair of suspenders?

13x+4y=487------>13x+4y=487----------->13x+4y=487
6x+2y=232-------->-2(6x+2y)=232*-2---->-12x-4y=-464

x=23----> 6(23)+2y=232------->138+2y=232----->2y=94--->y=47

x=ties y=suspenders
