a=(1800)/x+20

a = \frac{1800}{x} + 20

x = \frac{1800}{a - 20}; a \neq = 20

Solution steps

a = \frac{1800}{x} + 20

Move

20

to the left side

a - 20 = \frac{1800}{x}

Multiply both sides by

x

a x - 20 x = 1800

Factor

a x - 20 x : x (a - 20)

x (a - 20) = 1800

Divide both sides by

a - 20; a \neq = 20

x = \frac{1800}{a - 20}; a \neq = 20

b (x) = \frac{( x ^{2} - 4 )}{( x - 3 )}

3.834057 = \frac{0.75}{x}

\frac{6}{5} = \frac{2}{y}

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

\frac{3}{2 m + 4} = \frac{1}{m + 2} - 2
