48.72-13x=15.05
Pahekotia te -15x me 2x, ka -13x.
-13x=15.05-48.72
Tangohia te 48.72 mai i ngā taha e rua.
-13x=-33.67
Tangohia te 48.72 i te 15.05, ka -33.67.
x=\frac{-33.67}{-13}
Whakawehea ngā taha e rua ki te -13.
x=\frac{-3367}{-1300}
Whakarohaina te \frac{-33.67}{-13} mā te whakarea i te taurunga me te tauraro ki te 100.
x=\frac{259}{100}
Whakahekea te hautanga \frac{-3367}{-1300} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -13.
