Kua tāruatia ki te papatopenga
-2x+8=-4x+1
Pahekotia te 5x me -7x, ka -2x.
-2x+8+4x=1
Me tāpiri te 4x ki ngā taha e rua.
2x+8=1
Pahekotia te -2x me 4x, ka 2x.
2x=1-8
Tangohia te 8 mai i ngā taha e rua.
2x=-7
Tangohia te 8 i te 1, ka -7.
x=\frac{-7}{2}
Whakawehea ngā taha e rua ki te 2.
x=-\frac{7}{2}
Ka taea te hautanga \frac{-7}{2} te tuhi anō ko -\frac{7}{2} mā te tango i te tohu tōraro.
