Expression

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations that are formed according to rules which are dependent on the context.  

Given to us

Desired expression 3x-5

a.)  2x – 4 – 1 + x

Solving further

[tex]2x-4-1+x\\=3x-5[/tex]

As we can see on solving further the expression became equivalent to the desired expression.

b.)  –x + x + x – 1 – 1 – 1 – 1 – 1

Solving further

[tex]-x+x+x-1-1-1-1-1\\=-x+2x-5\\=x-5[/tex]

As we can see even on solving further the expression will not be equivalent to the desired expression.

c.)  –5 – 3x

[tex]-5-3x\\=-3x-5[/tex]

The expression was already solved and even when we rearranged the expression, the expression is not equivalent to the desired expression.

d.)  3x + 5

The expression is not equivalent to the desired expression as we can see that the value of 5 is not negative.

Therefore, the only correct option is A.
