Kua tāruatia ki te papatopenga
3q-19-10q=23
Tangohia te 10q mai i ngā taha e rua.
-7q-19=23
Pahekotia te 3q me -10q, ka -7q.
-7q=23+19
Me tāpiri te 19 ki ngā taha e rua.
-7q=42
Tāpirihia te 23 ki te 19, ka 42.
q=\frac{42}{-7}
Whakawehea ngā taha e rua ki te -7.
q=-6
Whakawehea te 42 ki te -7, kia riro ko -6.
