Kua tāruatia ki te papatopenga
8x-5=2x-6
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te x-3.
8x-5-2x=-6
Tangohia te 2x mai i ngā taha e rua.
6x-5=-6
Pahekotia te 8x me -2x, ka 6x.
6x=-6+5
Me tāpiri te 5 ki ngā taha e rua.
6x=-1
Tāpirihia te -6 ki te 5, ka -1.
x=\frac{-1}{6}
Whakawehea ngā taha e rua ki te 6.
x=-\frac{1}{6}
Ka taea te hautanga \frac{-1}{6} te tuhi anō ko -\frac{1}{6} mā te tango i te tohu tōraro.
