A smaller number is 3 less than half a larger number. The larger number is 10 times 1 less than the smaller number. Let xrepresent the smaller number, and let y represent the larger number. Which equations can be used to model the situation? Check all that apply.
1. x= 1/2y-3
2. 2x-y= -6
3. 2x-y= -3
4. x= 1/2 (y-3)
5. y-10 (x-1)
