Is it 16 or is it (16-x)?
16-x
Solve log2 16 – x = 7 log2 (16 - x) = log2 (128) 16-x=128 x = -112 x=-3
Okay...then it's \[2^{7}=16-x\]
128 = 16 - x x = -112

x = -112
Corey how are you getting -3

I didn't solve for x at the end because it's simple algebra...but... x + 7 = 4 -7 -7 ____________ x = -3
Hope the image helped somewhat.
