12w+8=w-14
Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te 3w+2.
12w+8-w=-14
Tangohia te w mai i ngā taha e rua.
11w+8=-14
Pahekotia te 12w me -w, ka 11w.
11w=-14-8
Tangohia te 8 mai i ngā taha e rua.
11w=-22
Tangohia te 8 i te -14, ka -22.
w=\frac{-22}{11}
Whakawehea ngā taha e rua ki te 11.
w=-2
Whakawehea te -22 ki te 11, kia riro ko -2.
