If m is a whole number, then 2m denotes a multiple of 2

Given m is a whole number

2m denotes a multiple of 2

∵ m is multiplied by 2

So, all values of 2m is multiplied by 2

So, given statement is True

0 is a solution of the equation x + 1 = 0

The equations x + 1 = 0 and 2x + 2 = 0 have the same solution.

The additive inverse of an integer x is 2x.

If x is a negative integer, – x is a positive integer.
