36x-360+48x=36
Whakamahia te āhuatanga tohatoha hei whakarea te -24 ki te 15-2x.
84x-360=36
Pahekotia te 36x me 48x, ka 84x.
84x=36+360
Me tāpiri te 360 ki ngā taha e rua.
84x=396
Tāpirihia te 36 ki te 360, ka 396.
x=\frac{396}{84}
Whakawehea ngā taha e rua ki te 84.
x=\frac{33}{7}
Whakahekea te hautanga \frac{396}{84} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 12.
