135+3x=272-17
Whakamahia te āhuatanga tohatoha hei whakarea te 45+x ki te 3.
135+3x=255
Tangohia te 17 i te 272, ka 255.
3x=255-135
Tangohia te 135 mai i ngā taha e rua.
3x=120
Tangohia te 135 i te 255, ka 120.
x=\frac{120}{3}
Whakawehea ngā taha e rua ki te 3.
x=40
Whakawehea te 120 ki te 3, kia riro ko 40.
