Question

In each of the thirteen colonies, X had the power to propose a budget, while Y had the "power of the purse"

Answer 1

X = The President

Y = Congress

Step-by-step explanation:

The Constitution gave the power of the purse, the nation's checkbook, to Congress. The Founders believed that this separation of powers would protect against monarchy and provide an important check on the executive branch.

The President has the power to propose a budget, who still has considerable agenda-setting power with the federal budget and submits a draft budget to Congress at the beginning of every year.

I hope this helps!
