Step-by-step explanation:

Bring -2 to the other side and A to the other side

<em>-</em><em>2</em><em> </em><em>Become </em><em>2</em><em> </em><em>because </em><em>of </em><em>flipping</em>

<em>And </em><em>A </em><em>becomes </em><em>-A </em><em>because </em><em>of </em><em>flipping</em>

<em>2</em><em>-</em><em>2</em><em>+</em><em>3</em><em>=</em><em>-A</em>

<em>-</em><em>A=</em><em>+</em><em>3</em>

<u>A=-3</u>
