36+x=12+3x
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 4+x.
36+x-3x=12
Tangohia te 3x mai i ngā taha e rua.
36-2x=12
Pahekotia te x me -3x, ka -2x.
-2x=12-36
Tangohia te 36 mai i ngā taha e rua.
-2x=-24
Tangohia te 36 i te 12, ka -24.
x=\frac{-24}{-2}
Whakawehea ngā taha e rua ki te -2.
x=12
Whakawehea te -24 ki te -2, kia riro ko 12.
