Kua tāruatia ki te papatopenga
-10+12p+40=18
Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te 3p+10.
30+12p=18
Tāpirihia te -10 ki te 40, ka 30.
12p=18-30
Tangohia te 30 mai i ngā taha e rua.
12p=-12
Tangohia te 30 i te 18, ka -12.
p=\frac{-12}{12}
Whakawehea ngā taha e rua ki te 12.
p=-1
Whakawehea te -12 ki te 12, kia riro ko -1.
