15^x = 15^y only if x=y. You are not given that and therefore cannot make that assumption. However, you can manipulate the equation to get (15^x)/(15^y) = (4^y)/(4^2) or 15^(x-y) = 4^(y-2). Looking at this equation we see an integer power of an odd number equal to an integer power of an even number...

Can Someone help with this please? The explanation skips a few steps that I don't understand so a nice little walk through will really help here! [15^x + (15^x * 15^1)]/(4^y) = 15^y 15^x[1 + 15] = 15^y * 4^y 15^x * 16 = 15^y * 4^y 15^x * 2^4 = 15^y * 2^(2y) Since the bases are the same on left hand...

C.
If the politician is going to say "He wants to build these, but he lives here so don't listen to him as he naturally doesn't support that structure. I want to build these." - logically I'd ask where do you live?
D - Don't see how that is irrelevant.

E is right.
You can't use "as" because we are comparing.

(2) is Insufficient because the question wants to know what does Y = ? If we plug in -8 into the formula: |3-y|=11 = |3--8|=11 = |3+8|=11 = |11|=11 = 11=11; So why can equal -8 here, but if we plug in 14 we can also get the answer of 11. |3-y|=11 = |3-14|=11 = |-11|=11 = 11=11 I think here you might...
