sweater = s, blouse = b

s + b = 57, s = 2b

2b + b = 57, 3b = 57, b = 19.

s = 2b = 2(19) = 38.

sweater costs 38 dollars, and blouse costs 19 dollars

x = -1; plug in y = 2(-1) - 1 = -2 - 1 = -3

x = 0; plug in y = 2(0) - 1 = 0 - 1 = -1

x = 1; plug in y = 2(1) - 1 = 2 - 1 = 1

x = 2; plug in y = 2(2) - 1 = 4 - 1 = 3
