solvefor k,r= k/(k-7)

solve for

k, r = \frac{k}{k - 7}

k = \frac{7 r}{r - 1}; r \neq = 1

Solution steps

r = \frac{k}{k - 7}

Multiply both sides by

k - 7

r (k - 7) = k

Expand

r (k - 7) : k r - 7 r

k r - 7 r = k

Move

7 r

to the right side

k r = k + 7 r

Move

k

to the left side

k r - k = 7 r

Factor

k r - k : k (r - 1)

k (r - 1) = 7 r

Divide both sides by

r - 1; r \neq = 1

k = \frac{7 r}{r - 1}; r \neq = 1

- 6 + \frac{x}{x - 6} = \frac{1}{x - 6}

\frac{5}{p} + 5 = - 10

\frac{b}{c} = a, c

x, f x = \frac{1}{x}

\frac{5}{x - 3} + \frac{2}{x + 1} = 1
