The cost of one sweatshirt is $19.
Step-by-step explanation:
Let,
Cost of one pair of jeans = x
Cost of one sweatshirt = y
According to given statement;

3x+4y=193 Eqn 2
Multiplying Eqn 1 by 2
Subtracting Eqn 2 from Eqn 3

First you will need to cross multiply.
5/x = 2/8
~ Do 5 times 8. =40
~ Then do 2 times x. =2x.
2x=40
/2 /2
~~Now divide each side by 2 and you should get x=20.
X=20
