Question 65693: Solve the equation:
sqrtx+4 = 3
I tried to keep this seperated because the square root is x + 4.
I am going to assume I need to make X equal the 3 leaving me with this:
X= -1
sqrt-1+4 = 3
Is this the right process?

You can put this solution on YOUR website!
Solve the equation:
sqrtx+4 = 3
sqrt%28x%2B4%29=3
%28sqrt%28x%2B4%29%29%5E2=%283%29%5E2
x%2B4=9
x%2B4-4=9-4
highlight%28x=5%29
Check to make sure this is a valid solution and not an extraneous one:
sqrt%285%2B4%29=3
sqrt%289%29=3
3=3 The solution is valid.
Happy Calculating!!!
