-x-\left(-10\right)=3x+2
Hei kimi i te tauaro o x-10, kimihia te tauaro o ia taurangi.
-x+10=3x+2
Ko te tauaro o -10 ko 10.
-x+10-3x=2
Tangohia te 3x mai i ngā taha e rua.
-4x+10=2
Pahekotia te -x me -3x, ka -4x.
-4x=2-10
Tangohia te 10 mai i ngā taha e rua.
-4x=-8
Tangohia te 10 i te 2, ka -8.
x=\frac{-8}{-4}
Whakawehea ngā taha e rua ki te -4.
x=2
Whakawehea te -8 ki te -4, kia riro ko 2.
