Given:

an expression is given as (2x + 1) - (4x + 3)

Find:

we have to find subtraction and then graph it.

Explanation:

The subtraction

$\begin{gathered} \left(2x+1\right)-(4x+3)=2x+1-4x-3=2x-4x+1-3 \\ =-2x-2=-2(x+1) \end{gathered}$

Therefore, (2x + 1) - (4x + 3) = -2 (x + 1)

Now we will draw the graph of -2(x + 1) as follows
