which flaw in the government created by the articles of confederation did Shay's rebellion make apparent?

A powerful central government

Explanation:

There were fewer taxes back in that day, which angered colonists. Protests in rural Massachusetts turned into direct action in August 1786 after the state legislature adjourned without considering the many petitions that had been sent to Boston. On August 29, 1786, a well-organized force of protestors formed in Northampton, Massachusetts, and successfully prevented the county court from sitting. The insurgents were organized into three major groups and intended to surround and attack the armory simultaneously. Shays had one group east of Springfield near Palmer, Luke Day had a second force across the Connecticut River in West Springfield, and the force under Eli Parsons was to the north at Chicopee. The rebels had planned their assault for January 25, but Day changed this at the last minute and sent a message to Shays indicating that he would not be ready to attack until the 26th. Day's message was intercepted by Shepard's men, so the militia of Shays and Parsons approached the armory on the 25th not knowing that they would have no support from the west; instead, they found Shepard's militia waiting for them. Shepard first ordered warning shots fired over the heads of Shays' men, and then he ordered two cannons to fire grapeshot. Four Shaysites were killed and 20 wounded. There was no musket fire from either side, and the rebel advance collapsed.

1.3x - 2 - (3.3x + 5) = 2x + 1

1.3x - 2 - 3.3x - 5 = 2x + 1

-2x - 7 = 2x + 1

-7 = 4x + 1

-8 = 4x

x = -2
