15x+6+x=6.8
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te 3x+1.2.
16x+6=6.8
Pahekotia te 15x me x, ka 16x.
16x=6.8-6
Tangohia te 6 mai i ngā taha e rua.
16x=0.8
Tangohia te 6 i te 6.8, ka 0.8.
x=\frac{0.8}{16}
Whakawehea ngā taha e rua ki te 16.
x=\frac{8}{160}
Whakarohaina te \frac{0.8}{16} mā te whakarea i te taurunga me te tauraro ki te 10.
x=\frac{1}{20}
Whakahekea te hautanga \frac{8}{160} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 8.
