Tohaina
Kua tāruatia ki te papatopenga
-x-\left(-2\right)=3\left(2x+3\right)
Hei kimi i te tauaro o x-2, kimihia te tauaro o ia taurangi.
-x+2=3\left(2x+3\right)
Ko te tauaro o -2 ko 2.
-x+2=6x+9
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 2x+3.
-x+2-6x=9
Tangohia te 6x mai i ngā taha e rua.
-7x+2=9
Pahekotia te -x me -6x, ka -7x.
-7x=9-2
Tangohia te 2 mai i ngā taha e rua.
-7x=7
Tangohia te 2 i te 9, ka 7.
x=\frac{7}{-7}
Whakawehea ngā taha e rua ki te -7.
x=-1
Whakawehea te 7 ki te -7, kia riro ko -1.
