It can be solved using triangle inequality.
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;
5x+2y=233 Eqn 1
3x+4y=193 Eqn 2
Multiplying Eqn 1 by 2
![2(5x+2y=233)\\10x+4y=466\ \ \ Eqn\ 3](https://tex.z-dn.net/?f=2%285x%2B2y%3D233%29%5C%5C10x%2B4y%3D466%5C%20%5C%20%5C%20Eqn%5C%203)
Subtracting Eqn 2 from Eqn 3
![(10x+4y)-(3x+4y)=466-193\\10x+4y-3x-4y=273\\7x=273](https://tex.z-dn.net/?f=%2810x%2B4y%29-%283x%2B4y%29%3D466-193%5C%5C10x%2B4y-3x-4y%3D273%5C%5C7x%3D273)
Dividing both sides by 7
![\frac{7x}{7}=\frac{273}{7}\\x=39](https://tex.z-dn.net/?f=%5Cfrac%7B7x%7D%7B7%7D%3D%5Cfrac%7B273%7D%7B7%7D%5C%5Cx%3D39)
Putting x=39 in Eqn 2
![3(39)+4y=193\\117+4y=193\\4y=193-117\\4y=76](https://tex.z-dn.net/?f=3%2839%29%2B4y%3D193%5C%5C117%2B4y%3D193%5C%5C4y%3D193-117%5C%5C4y%3D76)
Dividing both sides by 4
![\frac{4y}{4}=\frac{76}{4}\\y=19](https://tex.z-dn.net/?f=%5Cfrac%7B4y%7D%7B4%7D%3D%5Cfrac%7B76%7D%7B4%7D%5C%5Cy%3D19)
The cost of one sweatshirt is $19.
