Tohaina
Kua tāruatia ki te papatopenga
x-300+2\times 15=42
Whakaarohia te whārite tuatahi. Whakareatia te 50 ki te 6, ka 300.
x-300+30=42
Whakareatia te 2 ki te 15, ka 30.
x-270=42
Tāpirihia te -300 ki te 30, ka -270.
x=42+270
Me tāpiri te 270 ki ngā taha e rua.
x=312
Tāpirihia te 42 ki te 270, ka 312.
x=312 y=9 z=9 a=9 b=9
Kua oti te pūnaha te whakatau.
