Graph
Tohaina
Kua tāruatia ki te papatopenga
x+3+3x=-6
Me tāpiri te 3x ki ngā taha e rua.
4x+3=-6
Pahekotia te x me 3x, ka 4x.
4x=-6-3
Tangohia te 3 mai i ngā taha e rua.
4x=-9
Tangohia te 3 i te -6, ka -9.
x=\frac{-9}{4}
Whakawehea ngā taha e rua ki te 4.
x=-\frac{9}{4}
Ka taea te hautanga \frac{-9}{4} te tuhi anō ko -\frac{9}{4} mā te tango i te tohu tōraro.
