6x+3-6.2x=0
Tangohia te 6.2x mai i ngā taha e rua.
-0.2x+3=0
Pahekotia te 6x me -6.2x, ka -0.2x.
-0.2x=-3
Tangohia te 3 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-3}{-0.2}
Whakawehea ngā taha e rua ki te -0.2.
x=\frac{-30}{-2}
Whakarohaina te \frac{-3}{-0.2} mā te whakarea i te taurunga me te tauraro ki te 10.
x=15
Whakawehea te -30 ki te -2, kia riro ko 15.
