<em>Answer</em><em> </em><em>is given below with explanations</em><em>. </em>

Step-by-step explanation:

<em>Given</em><em> </em><em>that</em><em> </em><em>x</em><em> </em><em>=</em><em> </em><em>-2</em><em>.</em><em>5</em>

<em>To</em><em> </em><em>find</em><em> </em><em>the</em><em> </em><em>value</em><em> </em><em>of</em><em> </em><em>x</em><em>+</em><em>13</em>

<em>Ob</em><em> </em><em>substituting</em><em> </em><em>the</em><em> </em><em>value</em><em> </em><em>in</em><em> </em><em>the</em><em> </em><em>given equation</em><em> </em>

<em>we</em><em> </em><em>get</em><em> </em>

<em>=</em><em> </em><em>-2</em><em>.</em><em>5</em><em>+</em><em>13</em>

<em>=</em><em> </em><em>13</em><em> </em><em>-</em><em> </em><em>2</em><em>.</em><em>5</em><em> </em><em> </em><em> </em><em> </em><em>(</em><em>we</em><em> </em><em>can</em><em> </em><em>also</em><em> </em><em>write</em><em> </em><em>like</em><em> </em><em>this</em><em>)</em>

<em>=</em><em> </em><em>10</em><em>.</em><em>5</em>

<em>Therefore</em><em> </em><em>value</em><em> </em><em>of</em><em> </em><em>x</em><em> </em><em>+</em><em>13</em><em> </em><em>is</em><em> </em><em>10</em><em>.</em><em>5</em>
