Kua tāruatia ki te papatopenga
4x-12=9x\times 3
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.
4x-12=27x
Whakareatia te 9 ki te 3, ka 27.
4x-12-27x=0
Tangohia te 27x mai i ngā taha e rua.
-23x-12=0
Pahekotia te 4x me -27x, ka -23x.
-23x=12
Me tāpiri te 12 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
x=\frac{12}{-23}
Whakawehea ngā taha e rua ki te -23.
x=-\frac{12}{23}
Ka taea te hautanga \frac{12}{-23} te tuhi anō ko -\frac{12}{23} mā te tango i te tohu tōraro.
