Question 892825
How would I solve the equation "(11n-7)^2=9"?
I think the first step may be to convert to sqrt((11n-7))=9 but I am not entirely sure.
---------------
If you take the sqrt, you have to do both sides.
sqrt((11n-7)^2) = sqrt(9)
----------
(11n-7) = 3
Solve for n.
-----
Also
(11n-7) = -3
Solve for n
