And if so, is this the logic:
d/dx lne = [1/e * d/dx (e)] = [1/e * 0] = 0
and/or
d/dx lne = d/dx log(base e)(e) = d/dx 1 = 0
are there any other ways to make the point that d/dx of lne = 0?-d/dx (

Solve by elimination:
x - y + 2z = - 7
y + z = 1
x = 2y + 3z-set the first equation = to x, so x= y-2z-7
next, plug into the x in the third equation: y-2z-7=2y+3z
for the second equation, solve for e
