A smaller number is 3 less than half a larger number. The larger number is 10 times 1 less than the smaller number. Let x represent the smaller number, and let y represent the larger number.

Which equations can be used to model the
situation? Check all that apply.

x = 1/2y - 3

2x - y = -6

2x - y = -3

x = 1/2(y - 3)

y = 10 (x - 1)
