So what's the rule that governs the division that was done to obtain the 3 but retain the 2x-1 Sorry I'm a bit dense on this subject... for example is the rule: xy-xz=((xy-xz)/xz)xz

3(2x-2)=3(213) divide by 3 on both sides 2x-2=213 add 2 to both the exponents 2x=215 x must equal 15. Okay... so I'm still unclear of how you got to 3(2x-2) on the LHS I know how we got the 3 but what were the thoughts behind that and how did we retain the (2x-2) THANK...

is it? 2x-(x-2)-2x-2-(x-2) 4-1=3

is it just 2? so it's 22=4 so 4=3(213)? That doesn't seem right...

so we have to simplify the left side of the equation first? 2x-2x-2=3(213) Then 2x-(x-2)=3(213) Then...?

or is it... 2x/x-2?

wait... is it 22x-2?

Holy Poop tim! my brain is about to explode... I don't know. :)

Would it be 2x-(x-2)?

Homework Statement I'm studying for the GMAT and the study materials do not include how to solve this equation. I need to know how to solve it without a calculator. Homework Equations If 2^x - 2^x-2 = 3(2^13), what is the value of X? The Attempt at a Solution The answer key says...
