Ngā Upane mō te Whakaoti Whārite Rārangi

Pahekotia te 15x me -60x, ka -45x.

$$-45x-3-3+30=9x-9+3x$$

Tangohia te 3 i te -3, ka -6.

$$-45x-6+30=9x-9+3x$$

Tāpirihia te -6 ki te 30, ka 24.

$$-45x+24=9x-9+3x$$

Pahekotia te 9x me 3x, ka 12x.

$$-45x+24=12x-9$$

Tangohia te 12x mai i ngā taha e rua.

$$-45x+24-12x=-9$$

Pahekotia te -45x me -12x, ka -57x.

$$-57x+24=-9$$

Tangohia te 24 mai i ngā taha e rua.

$$-57x=-9-24$$

Tangohia te 24 i te -9, ka -33.

$$-57x=-33$$

Whakawehea ngā taha e rua ki te -57.

$$x=\frac{-33}{-57}$$

Whakahekea te hautanga \frac{-33}{-57} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -3.

$$x=\frac{11}{19}$$
