6x+2=3x
Me whakarea ngā taha e rua o te whārite ki te 6, arā, te tauraro pātahi he tino iti rawa te kitea o 3,2.
6x+2-3x=0
Tangohia te 3x mai i ngā taha e rua.
3x+2=0
Pahekotia te 6x me -3x, ka 3x.
3x=-2
Tangohia te 2 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-2}{3}
Whakawehea ngā taha e rua ki te 3.
x=-\frac{2}{3}
Ka taea te hautanga \frac{-2}{3} te tuhi anō ko -\frac{2}{3} mā te tango i te tohu tōraro.
