Tohaina
Kua tāruatia ki te papatopenga
4x+5-2x=0
Tangohia te 2x mai i ngā taha e rua.
2x+5=0
Pahekotia te 4x me -2x, ka 2x.
2x=-5
Tangohia te 5 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-5}{2}
Whakawehea ngā taha e rua ki te 2.
x=-\frac{5}{2}
Ka taea te hautanga \frac{-5}{2} te tuhi anō ko -\frac{5}{2} mā te tango i te tohu tōraro.
