(y+4.5)/y = 28/10

\frac{y + 4.5}{y} = \frac{28}{10}

y = \frac{5}{2}

Decimal Notation

y = 2.5

Solution steps

\frac{y + 4.5}{y} = \frac{28}{10}

Cross multiply

10 y + 45 = y \cdot 28

Move

45

to the right side

10 y = y \cdot 28 - 45

Move

y 28

to the left side

- 18 y = - 45

Divide both sides by

- 18

y = \frac{5}{2}

Verify Solutions

Find undefined (singularity) points:

y = 0

Combine undefined points with solutions:

y = \frac{5}{2}

\frac{3}{x - 2} + \frac{8}{x + 3} = 2

\frac{5}{p + 5} = - 10

\frac{2}{x} = - 3

(x - 3)^{2} = \frac{1}{( x - 3 ) ^{2}}

\frac{3 x}{x - 1} + \frac{1}{x} = 4
