statuscvo [17]
<h3>Solution : </h3>

<h3>y = 2(1 + 5 \sqrt{967} )</h3>

<h3>Step by Step explanation:</h3>

<h3>1.Switch sides</h3><h3 /><h3>y\sqrt{6}  =  \sqrt{24 }  +  \sqrt{967}  \sqrt{600}</h3><h3 /><h2 /><h3>2.Simplify√24 + √967 √600</h3>

<h3>y \sqrt{6}   = 2 \sqrt{6}  + 10 \sqrt{5802}</h3>

<h3>3.Divide both side by √6</h3>

<h3>\frac{y \sqrt{6} }{ \sqrt{6} }  =  \frac{2 \sqrt{6} }{ \sqrt{6 } }  +  \frac{10 \sqrt{5802} }{ \sqrt{6} }</h3><h3>4.Simplify</h3><h3 /><h3>y = 2(1 + 5 \sqrt{967} )</h3>
