Hi student, let me help you out! :)

We are asked to solve the equation $\pmb{2x+3=-1}$.

$\triangle~\fbox{\bf{KEY:}}$

• The goal is to isolate x.

First, subtract 3 from both sides of the equal sign:

$\mathrm{2x=-1-3}$

$\mathrm{2x=-4}$

Now, divide both sides by 2:

$\mathrm{x=-2}$

Hope it helps you out! :D
