Whakaoti mō x, b
x=-15
b=3
Tohaina
Kua tāruatia ki te papatopenga
x=-3\times 5
Whakaarohia te whārite tuatahi. Me whakarea ngā taha e rua ki te 5.
x=-15
Whakareatia te -3 ki te 5, ka -15.
b=\frac{21}{7}
Whakaarohia te whārite tuarua. Whakawehea ngā taha e rua ki te 7.
b=3
Whakawehea te 21 ki te 7, kia riro ko 3.
x=-15 b=3
Kua oti te pūnaha te whakatau.
