I am having so much trouble with these kinds of equations. Can someone please help me:confused:

Solve for 'x':

2^2x-1 - 6.2^x-1 + 4 = 0

and...

2^2x - 5.2^x+1 + 16 = 0

Well, I did it without the multiplying through by 2 and got

x = 2 or 1

and they appear to work.

Thanx heaps for helping me out - Jan 27th 2008, 06:09 PMmr fantastic
