(2r-3)/r = 7/5

\frac{2 r - 3}{r} = \frac{7}{5}

r = 5

Solution steps

\frac{2 r - 3}{r} = \frac{7}{5}

Cross multiply

10 r - 15 = r \cdot 7

Move

15

to the right side

10 r = r \cdot 7 + 15

Move

r 7

to the left side

3 r = 15

Divide both sides by

3

r = 5

Find undefined (singularity) points:

r = 0

Combine undefined points with solutions:

r = 5

(x + 6)^{- 1} = x^{- 1} + x

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

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

a, g = b - \frac{c}{a}
