What is wrong with this argument?Check all that apply.

Suppose x=2

2x=4

2x + 1 =5

Nothing.

Punctuation is missing.Each sentence needs to be terminated with a period (.).

The logical glue is missing.Lines 2 is a consequence of line 1, and line 3 is a consequence of line 2. Words and phrases like "Thus", "Therefore", "It follows", etc. need to be used to make it clear that we are drawing conclusions.

The assumption that x is an integer was not stated.Line 1 should have been "Suppose x is an integer and x = 2".
