Question

1 upon x - 1 upon y = 0

Answer 1

Answer:

Step-by-step explanation:

a) 1/x -1/y = 0

Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by xy, the least common multiple of x,y.

y−x=0

Subtract y from both sides. Anything subtracted from zero gives its negation.

−x=−y

Cancel out −1 on both sides.

x=y

Variable x cannot be equal to 0.

x=y, x $\neq$y. #Solving for Y

b) 1/x -1/y = 0

Variable y cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by xy, the least common multiple of x,y.

y−x=0

Add x to both sides. Anything plus zero gives itself.

y=x

Variable y cannot be equal to 0.

y=x, y $\neq$0. #Solving for X.
