Kua tāruatia ki te papatopenga
2x-60=16x
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te x-30.
2x-60-16x=0
Tangohia te 16x mai i ngā taha e rua.
-14x-60=0
Pahekotia te 2x me -16x, ka -14x.
-14x=60
Me tāpiri te 60 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
x=\frac{60}{-14}
Whakawehea ngā taha e rua ki te -14.
x=-\frac{30}{7}
Whakahekea te hautanga \frac{60}{-14} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
