3/(7x)=2

\frac{3}{7 x} = 2

x = \frac{3}{14}

Decimal Notation

x = 0.21428 \dots

Solution steps

\frac{3}{7 x} = 2

Multiply both sides by

x

\frac{3}{7} = 2 x

Switch sides

2 x = \frac{3}{7}

Divide both sides by

2

x = \frac{3}{14}

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = \frac{3}{14}

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

- 4 = r^{- 4}

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

\frac{X - 70}{X} = \frac{7}{20}

\frac{x - 5}{( x - 1 ) ^{3}} = 0
