80=((x+300)x)/((x+300)+x)

80 = \frac{( x + 300 ) x}{( x + 300 ) + x}

x = 100, x = - 240

Solution steps

80 = \frac{( x + 300 ) x}{( x + 300 ) + x}

Simplify

\frac{( x + 300 ) x}{( x + 300 ) + x} : \frac{x ( x + 300 )}{2 x + 300}

80 = \frac{x ( x + 300 )}{2 x + 300}

Multiply both sides by

2 x + 300

80 (2 x + 300) = x (x + 300)

Solve

80 (2 x + 300) = x (x + 300) : x = 100, x = - 240

x = 100, x = - 240

Verify Solutions

Find undefined (singularity) points:

x = - 150

Combine undefined points with solutions:

x = 100, x = - 240

\frac{28}{21} = \frac{35 - x}{x}

2.5 = \frac{2612.5}{x}

\frac{1}{1 + 19.21 X} = 0.005

x, y = \frac{6}{9 - x}

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