Kua tāruatia ki te papatopenga
9x-4=-9\times 2
Me whakarea ngā taha e rua ki te 2.
9x-4=-18
Whakareatia te -9 ki te 2, ka -18.
9x=-18+4
Me tāpiri te 4 ki ngā taha e rua.
9x=-14
Tāpirihia te -18 ki te 4, ka -14.
x=\frac{-14}{9}
Whakawehea ngā taha e rua ki te 9.
x=-\frac{14}{9}
Ka taea te hautanga \frac{-14}{9} te tuhi anō ko -\frac{14}{9} mā te tango i te tohu tōraro.
