(x-3)/x = 3/5

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

x = \frac{15}{2}

Decimal

x = 7.5

Solution steps

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

Cross multiply

5 x - 15 = x \cdot 3

Move

15

to the right side

5 x = x \cdot 3 + 15

Move

x 3

to the left side

2 x = 15

Divide both sides by

2

x = \frac{15}{2}

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = \frac{15}{2}

A X (D + BX)^{- 1} = C

f, f (x)^{- 1} (x) = x^{3} + x

\frac{2 x - 3}{x - 1} = \frac{8 x + 1}{4 x + 5}

\frac{1}{5 x} + \frac{x + 4}{x} = \frac{6}{5}

\frac{1}{7} - \frac{1}{2} = \frac{1}{x}
