Kua tāruatia ki te papatopenga
4\times 3x-3x=30
Me whakarea ngā taha e rua o te whārite ki te 12, arā, te tauraro pātahi he tino iti rawa te kitea o 3,4,2.
12x-3x=30
Whakareatia te 4 ki te 3, ka 12.
9x=30
Pahekotia te 12x me -3x, ka 9x.
x=\frac{30}{9}
Whakawehea ngā taha e rua ki te 9.
x=\frac{10}{3}
Whakahekea te hautanga \frac{30}{9} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.
