2x+10=12x+6
Whakareatia te 2 ki te 6, ka 12.
2x+10-12x=6
Tangohia te 12x mai i ngā taha e rua.
-10x+10=6
Pahekotia te 2x me -12x, ka -10x.
-10x=6-10
Tangohia te 10 mai i ngā taha e rua.
-10x=-4
Tangohia te 10 i te 6, ka -4.
x=\frac{-4}{-10}
Whakawehea ngā taha e rua ki te -10.
x=\frac{2}{5}
Whakahekea te hautanga \frac{-4}{-10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -2.
