An agency has be formed that is called "The National Recovery Administration (NRA)" was a prime New Deal agency formed by U.S. President Franklin D Roosevelt in 1933.

Roosevelt's purpose was clear to form the ideological balance of the Court so that it would stop striking down his New Deal legislation and this was called Court-Packing Plan. As a result, the plan was widely and vehemently criticized.

"The National Industrial Recovery Act" of 1933 was declared to be unconstitutional in May 1935 because the court tribunal stated that the NIRA extended the lawmaking authorities to the NRA in violating the allocation of the constitution of such powers to Congress.

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
