Answer:
<h2><em><u>x</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>-</u></em><em><u>4</u></em></h2>
Step-by-step explanation:
<h3>
<u>Given</u> <u> </u> <u>Equation</u> <u>:</u> </h3>
<h3>
<u>Question</u> <u>:</u> </h3>
Whether x has one solution or infinite solutions or no solutions?
<h3>
<u>Solution</u> <u>:</u> </h3>
=> 3x + 9 = 2x + 5
<em>(</em><em>On</em><em> </em><em>shifting</em><em> </em><em>like</em><em> </em><em>terms</em><em> </em><em>to</em><em> </em><em>one</em><em> </em><em>side</em><em> </em><em>we</em><em> </em><em>get</em><em>)</em> => 3x - 2x = 5 - 9
<em>(</em><em>On</em><em> </em><em>subtracting</em><em>)</em> => x = - 4
<h3>
<u>Result</u> <u>:</u> </h3>
<em><u>Hence</u></em> <em><u>,</u></em> <em><u> </u></em> <em><u>x</u></em> <em><u> </u></em> <em><u>has</u></em> <em><u> </u></em> <em><u>only</u></em> <em><u> </u></em> <em><u>one</u></em> <em><u> </u></em> <em><u>solution</u></em> <em><u> </u></em> <em><u>that</u></em> <em><u> </u></em> <em><u>is</u></em> <em><u>,</u></em> <em><u> </u></em> <em><u>x</u></em> <em><u> </u></em> <em><u>=</u></em> <em><u> </u></em> <em><u>-</u></em> <em><u>4</u></em> <em><u> </u></em> <em><u>(</u></em> <em><u>Ans</u></em> <em><u>)</u></em>
