Question 47845
solve the equation
{{{sqrt(3x-3)-9=0}}}

solving for x.
Fisrt we want to isolate the sqrt so we move the -9 to the other side of the equal sign which gives us..
{{{sqrt(3x-3)=9}}}
Now we have to eliminate the sqrt by squaring it which gives us..

{{{(sqrt(3x-3))^2=(9)^2}}}
Since the sqrt is now removed your equation will look like this..
{{{3x-3=81}}}
So we proceed to combining like terms
{{{3x=81}}}
{{{x=81/3}}}
Answer: x= 27
