Kua tāruatia ki te papatopenga
4x+1-x=-7
Tangohia te x mai i ngā taha e rua.
3x+1=-7
Pahekotia te 4x me -x, ka 3x.
3x=-7-1
Tangohia te 1 mai i ngā taha e rua.
3x=-8
Tangohia te 1 i te -7, ka -8.
x=\frac{-8}{3}
Whakawehea ngā taha e rua ki te 3.
x=-\frac{8}{3}
Ka taea te hautanga \frac{-8}{3} te tuhi anō ko -\frac{8}{3} mā te tango i te tohu tōraro.
