(5x)/(4(x+2))= 1/7

\frac{5 x}{4 ( x + 2 )} = \frac{1}{7}

x = \frac{8}{31}

Decimal Notation

x = 0.25806 \dots

Solution steps

\frac{5 x}{4 ( x + 2 )} = \frac{1}{7}

Cross multiply

35 x = 4 x + 8

Move

4 x

to the left side

31 x = 8

Divide both sides by

31

x = \frac{8}{31}

Verify Solutions

Find undefined (singularity) points:

x = - 2

Combine undefined points with solutions:

x = \frac{8}{31}

1 - x - \frac{12}{36 x + 6} = 0

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

\frac{4 x - 5}{2 x + 7} = \frac{2}{5}

5 (4 + r) = \frac{1}{2 ( 40 + 10 r )}

\frac{60}{15} = \frac{100}{y}
