Whakahekea te hautanga \frac{10}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 10.

$$\left(\frac{1}{10}-5\right)\left(y-2\right)$$

Me tahuri te 5 ki te hautau \frac{50}{10}.

$$\left(\frac{1}{10}-\frac{50}{10}\right)\left(y-2\right)$$

Tā te mea he rite te tauraro o \frac{1}{10} me \frac{50}{10}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{1-50}{10}\left(y-2\right)$$

Tangohia te 50 i te 1, ka -49.

$$-\frac{49}{10}\left(y-2\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te -\frac{49}{10} ki te y-2.

$$-\frac{49}{10}y-\frac{49}{10}\left(-2\right)$$

Tuhia te -\frac{49}{10}\left(-2\right) hei hautanga kotahi.

$$-\frac{49}{10}y+\frac{-49\left(-2\right)}{10}$$

Whakareatia te -49 ki te -2, ka 98.

$$-\frac{49}{10}y+\frac{98}{10}$$

Whakahekea te hautanga \frac{98}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
