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