Kua tāruatia ki te papatopenga
2x-3-\left(3x-1\right)=2x+2
Whakareatia ngā taha e rua o te whārite ki te 2.
2x-3-3x-\left(-1\right)=2x+2
Hei kimi i te tauaro o 3x-1, kimihia te tauaro o ia taurangi.
2x-3-3x+1=2x+2
Ko te tauaro o -1 ko 1.
-x-3+1=2x+2
Pahekotia te 2x me -3x, ka -x.
-x-2=2x+2
Tāpirihia te -3 ki te 1, ka -2.
-x-2-2x=2
Tangohia te 2x mai i ngā taha e rua.
-3x-2=2
Pahekotia te -x me -2x, ka -3x.
-3x=2+2
Me tāpiri te 2 ki ngā taha e rua.
-3x=4
Tāpirihia te 2 ki te 2, ka 4.
x=\frac{4}{-3}
Whakawehea ngā taha e rua ki te -3.
x=-\frac{4}{3}
Ka taea te hautanga \frac{4}{-3} te tuhi anō ko -\frac{4}{3} mā te tango i te tohu tōraro.
