1290= k/(10)+h/s

1290 = \frac{k}{10} + \frac{h}{s}

s = \frac{10 h}{12900 - k}; k \neq = 12900

Solution steps

1290 = \frac{k}{10} + \frac{h}{s}

Multiply both sides by

s

1290 s = \frac{k s}{10} + h

Multiply both sides by

10

12900 s = k s + 10 h

Move

k s

to the left side

12900 s - k s = 10 h

Factor

12900 s - k s : s (12900 - k)

s (12900 - k) = 10 h

Divide both sides by

12900 - k; k \neq = 12900

s = \frac{10 h}{12900 - k}; k \neq = 12900

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

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

\frac{x ^{2}}{x + 100} = 50

\frac{x - 2}{x - 1} = \frac{4}{x + 2}

\frac{10}{5 x - 9} = \frac{8}{2 x - 8}
