Tohaina
Kua tāruatia ki te papatopenga
15x-49+2x=36
Whakaarohia te whārite tuatahi. Me tāpiri te 2x ki ngā taha e rua.
17x-49=36
Pahekotia te 15x me 2x, ka 17x.
17x=36+49
Me tāpiri te 49 ki ngā taha e rua.
17x=85
Tāpirihia te 36 ki te 49, ka 85.
x=\frac{85}{17}
Whakawehea ngā taha e rua ki te 17.
x=5
Whakawehea te 85 ki te 17, kia riro ko 5.
x=5 y=22 z=22 a=22 b=22 c=22 d=22
Kua oti te pūnaha te whakatau.
