(X-70)/X = 7/20

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

X = \frac{1400}{13}

Decimal Notation

X = 107.69230 \dots

Solution steps

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

Cross multiply

20 X - 1400 = X \cdot 7

Move

1400

to the right side

20 X = X \cdot 7 + 1400

Move

X 7

to the left side

13 X = 1400

Divide both sides by

13

X = \frac{1400}{13}

Verify Solutions

Find undefined (singularity) points:

X = 0

Combine undefined points with solutions:

X = \frac{1400}{13}

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

x^{- 2} - 6 x^{- 1} + 8 = 0

\frac{11}{x - 5} = - \frac{3}{7 + 2 x}

\frac{3}{x} = \frac{x}{12}

\frac{4}{x} - 5 = \frac{18}{2 x}
