1.Find the value of when = 4.
My attempt: == 4
When checked on a calculator it doesn't work. I don't understand what to do. Is there a way to solve this without using calculators?
2. Solve the equation
I don't have an attempt since I can't understand what operation to use.
Whoops, wrong category. Can I request for a Moderator (if there is one in here) to relocate this to Algebra?
