Kua tāruatia ki te papatopenga
3-9x=31x-10
Pahekotia te 24x me 7x, ka 31x.
3-9x-31x=-10
Tangohia te 31x mai i ngā taha e rua.
3-40x=-10
Pahekotia te -9x me -31x, ka -40x.
-40x=-10-3
Tangohia te 3 mai i ngā taha e rua.
-40x=-13
Tangohia te 3 i te -10, ka -13.
x=\frac{-13}{-40}
Whakawehea ngā taha e rua ki te -40.
x=\frac{13}{40}
Ka taea te hautanga \frac{-13}{-40} te whakamāmā ki te \frac{13}{40} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
