[tex]\frac{\sqrt{4x+15} }{\sqrt{x} } =3[/tex]

Answer:

3

Step-by-step explanation:

Multiply both sides by x to get rid or the denominator: [tex]\sqrt{4x+15}=3\sqrt{x}[/tex]

Get rid of the square root by squaring both sides:[tex]\left(\sqrt{4x+15}\right)^2=\left(3\sqrt{x}\right)^2[/tex] = 4x + 15 = 9x

Just solve for x.

Hope this helps!!
