Kua tāruatia ki te papatopenga
7x+8-4x=4
Tangohia te 4x mai i ngā taha e rua.
3x+8=4
Pahekotia te 7x me -4x, ka 3x.
3x=4-8
Tangohia te 8 mai i ngā taha e rua.
3x=-4
Tangohia te 8 i te 4, ka -4.
x=\frac{-4}{3}
Whakawehea ngā taha e rua ki te 3.
x=-\frac{4}{3}
Ka taea te hautanga \frac{-4}{3} te tuhi anō ko -\frac{4}{3} mā te tango i te tohu tōraro.
