Tohaina
Kua tāruatia ki te papatopenga
120x=-70x+40
Ko te tau i tāpiria he kore ka hua koia tonu.
120x+70x=40
Me tāpiri te 70x ki ngā taha e rua.
190x=40
Pahekotia te 120x me 70x, ka 190x.
x=\frac{40}{190}
Whakawehea ngā taha e rua ki te 190.
x=\frac{4}{19}
Whakahekea te hautanga \frac{40}{190} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 10.
