3x+12=6x-36
Whakareatia ngā taha e rua o te whārite ki te 6.
3x+12-6x=-36
Tangohia te 6x mai i ngā taha e rua.
-3x+12=-36
Pahekotia te 3x me -6x, ka -3x.
-3x=-36-12
Tangohia te 12 mai i ngā taha e rua.
-3x=-48
Tangohia te 12 i te -36, ka -48.
x=\frac{-48}{-3}
Whakawehea ngā taha e rua ki te -3.
x=16
Whakawehea te -48 ki te -3, kia riro ko 16.
