Kua tāruatia ki te papatopenga
5x+7=1
Pahekotia te 4x me x, ka 5x.
5x=1-7
Tangohia te 7 mai i ngā taha e rua.
5x=-6
Tangohia te 7 i te 1, ka -6.
x=\frac{-6}{5}
Whakawehea ngā taha e rua ki te 5.
x=-\frac{6}{5}
Ka taea te hautanga \frac{-6}{5} te tuhi anō ko -\frac{6}{5} mā te tango i te tohu tōraro.
