This is a system of equations.
Let b be the blouse, and s be the sweater
b + s = 74
s = 8 + 2b
Now, solve for the b
b + 8 + 2b = 74
3b = 66
b = 22
The blouse was $22

We'll use b for the price of the blouse and s for the price of the sweater.
b + s = 74
2b + 8 = s
Now we can plug 2b + 8 in for s.
b + (2b + 8) = 74
3b + 8 = 74
3b = 66
b = $22
