Answer:

[tex]x=4[/tex]

Step-by-step explanation:

subtract [tex]\sqrt{3x-12}[/tex] from both sides:

[tex]\sqrt{2x-8}=-\sqrt{3x-12}[/tex]

square to both sides:

[tex](\sqrt{2x-8})^{2} =-(\sqrt{3x-12})^{2} \\2x-8=-(3x-12)[/tex]

Add 3x-12 to both sides:

[tex]2x-8+3x-12=0\\5x-20=0[/tex]

Add 20to both sides:

[tex]5x=20[/tex]

Finally, Divide both sides by 5:

[tex]x=\frac{20}{5}=4[/tex]
