Question 49901
a.) Remember: anything divided by zero is undefined....{{{x}}} can not be zero
3/x - 1/6 = 1/x multiply all the terms by {{{x}}}
3 - x/6 = 1 multiply all the terms by {{{6}}}
18 - x = 6
-x = -12
x = 12
b.) {{{y}}} can not equal positive one
13/(y - 1) - 3 = 1/(y - 1)
13 - 3(y - 1) = 1
13 - 3y + 3 = 1
-3y = -15
y = 5
