2x+29+x+26+29=135
Pahekotia te x me x, ka 2x.
3x+29+26+29=135
Pahekotia te 2x me x, ka 3x.
3x+55+29=135
Tāpirihia te 29 ki te 26, ka 55.
3x+84=135
Tāpirihia te 55 ki te 29, ka 84.
3x=135-84
Tangohia te 84 mai i ngā taha e rua.
3x=51
Tangohia te 84 i te 135, ka 51.
x=\frac{51}{3}
Whakawehea ngā taha e rua ki te 3.
x=17
Whakawehea te 51 ki te 3, kia riro ko 17.
