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

solve for

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

x = \frac{y + y f}{f - 1}; f \neq = 1

Solution steps

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

Multiply both sides by

x - y

f (x - y) = x + y

Expand

f (x - y) : x f - y f

x f - y f = x + y

Move

y f

to the right side

x f = x + y + y f

Move

x

to the left side

x f - x = y + y f

Factor

x f - x : x (f - 1)

x (f - 1) = y + y f

Divide both sides by

f - 1; f \neq = 1

x = \frac{y + y f}{f - 1}; f \neq = 1

y, x = \frac{- 2 y}{y - 1}

k, r = \frac{k}{k - 8}

\frac{14}{y} + \frac{26}{y} = 5

c, 70% + \frac{f}{c} = 1

x = x^{- 1}
