Graph
Tohaina
Kua tāruatia ki te papatopenga
x-2=-6x-8
Whakareatia te -3 ki te 2, ka -6.
x-2+6x=-8
Me tāpiri te 6x ki ngā taha e rua.
7x-2=-8
Pahekotia te x me 6x, ka 7x.
7x=-8+2
Me tāpiri te 2 ki ngā taha e rua.
7x=-6
Tāpirihia te -8 ki te 2, ka -6.
x=\frac{-6}{7}
Whakawehea ngā taha e rua ki te 7.
x=-\frac{6}{7}
Ka taea te hautanga \frac{-6}{7} te tuhi anō ko -\frac{6}{7} mā te tango i te tohu tōraro.
