-2-3x=2x-1-\left(-x\right)
Hei kimi i te tauaro o 1-x, kimihia te tauaro o ia taurangi.
-2-3x=2x-1+x
Ko te tauaro o -x ko x.
-2-3x=3x-1
Pahekotia te 2x me x, ka 3x.
-2-3x-3x=-1
Tangohia te 3x mai i ngā taha e rua.
-2-6x=-1
Pahekotia te -3x me -3x, ka -6x.
-6x=-1+2
Me tāpiri te 2 ki ngā taha e rua.
-6x=1
Tāpirihia te -1 ki te 2, ka 1.
x=\frac{1}{-6}
Whakawehea ngā taha e rua ki te -6.
x=-\frac{1}{6}
Ka taea te hautanga \frac{1}{-6} te tuhi anō ko -\frac{1}{6} mā te tango i te tohu tōraro.
