[tex] \frac{y}{y} - 5 + \frac{1}{y} + 8 [/tex]

→[tex](1 - 5) + \frac{1}{y} + 8[/tex]

→[tex]-4 = \frac{ - 4}{1} = \frac{ - 4 \: • \: y}{y} [/tex]

→[tex] \frac{ - 4 \: • \: y + 1}{y} = \frac{1 - 4y}{y} [/tex]

→[tex] \frac{(1 - 4y)}{y} + 8[/tex]

→[tex]8 = \frac{8}{1} = \frac{8 \: • \: y}{y} [/tex]

→[tex] \frac{(1 - 4y) + 8 \: • \: y}{y} = \frac{4y + 1}{y} [/tex]

→[tex] \frac{4y + 1}{y} [/tex]
