solvefor x,y=(x-t)/(x+t)

solve for

x, y = \frac{x - t}{x + t}

x = \frac{- t - y t}{y - 1}; y \neq = 1

Solution steps

y = \frac{x - t}{x + t}

Multiply both sides by

x + t

y (x + t) = x - t

Expand

y (x + t) : x y + y t

x y + y t = x - t

Move

y t

to the right side

x y = x - t - y t

Move

x

to the left side

x y - x = - t - y t

Factor

x y - x : x (y - 1)

x (y - 1) = - t - y t

Divide both sides by

y - 1; y \neq = 1

x = \frac{- t - y t}{y - 1}; y \neq = 1

\frac{x - 119}{x + 7} = - 5

\frac{3}{x - 2} + \frac{3}{x + 2} = 2

\frac{4 x}{x ^{2} - 25} = \frac{1}{5 - x}

y, 3 + \frac{5}{x} - y = 2

\frac{2 a - 3}{4 a - 5} = \frac{2}{5}
