Question 65693
Solve the equation:

sqrtx+4  = 3

{{{sqrt(x+4)=3}}}
{{{(sqrt(x+4))^2=(3)^2}}}
{{{x+4=9}}}
{{{x+4-4=9-4}}}
{{{highlight(x=5)}}}
Check to make sure this is a valid solution and not an extraneous one:
{{{sqrt(5+4)=3}}}
{{{sqrt(9)=3}}}
{{{3=3}}} The solution is valid.
Happy Calculating!!!
