9x+3=13-6x
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 3x+1.
9x+3+6x=13
Me tāpiri te 6x ki ngā taha e rua.
15x+3=13
Pahekotia te 9x me 6x, ka 15x.
15x=13-3
Tangohia te 3 mai i ngā taha e rua.
15x=10
Tangohia te 3 i te 13, ka 10.
x=\frac{10}{15}
Whakawehea ngā taha e rua ki te 15.
x=\frac{2}{3}
Whakahekea te hautanga \frac{10}{15} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.
