4+4x+3+x+4+2x-6=0
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 2+2x.
7+4x+x+4+2x-6=0
Tāpirihia te 4 ki te 3, ka 7.
7+5x+4+2x-6=0
Pahekotia te 4x me x, ka 5x.
11+5x+2x-6=0
Tāpirihia te 7 ki te 4, ka 11.
11+7x-6=0
Pahekotia te 5x me 2x, ka 7x.
5+7x=0
Tangohia te 6 i te 11, ka 5.
7x=-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}{7}
Whakawehea ngā taha e rua ki te 7.
x=-\frac{5}{7}
Ka taea te hautanga \frac{-5}{7} te tuhi anō ko -\frac{5}{7} mā te tango i te tohu tōraro.
