Graph
Tohaina
Kua tāruatia ki te papatopenga
x+3+4x=0
Me tāpiri te 4x ki ngā taha e rua.
5x+3=0
Pahekotia te x me 4x, ka 5x.
5x=-3
Tangohia te 3 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-3}{5}
Whakawehea ngā taha e rua ki te 5.
x=-\frac{3}{5}
Ka taea te hautanga \frac{-3}{5} te tuhi anō ko -\frac{3}{5} mā te tango i te tohu tōraro.
