Question

Solve 1/x + 1/y= 1 for y

please and thank you

Answer 1

make the two fractions have the same denomincator. Add. Eliminate the denominator. Solve.

Answer 2

1/x 1/y

1/x 1/1

1/x+1 is the answer

Answer 3

Solve 1/x + 1/y= 1 for y

First of all, subtract 1/x (using basic algebra laws) from both sides.

1/y = 1 - 1/X

Then you can invert each side, using the reciprocals, to move the y to the numerator.

y = 1/ (1-1/X)

This is your answer.
