Tohaina
Kua tāruatia ki te papatopenga
m=-9\times 2
Whakaarohia te whārite tuatahi. Me whakarea ngā taha e rua ki te 2.
m=-18
Whakareatia te -9 ki te 2, ka -18.
x=\frac{42}{7}
Whakaarohia te whārite tuarua. Whakawehea ngā taha e rua ki te 7.
x=6
Whakawehea te 42 ki te 7, kia riro ko 6.
m=-18 x=6
Kua oti te pūnaha te whakatau.
