Kua tāruatia ki te papatopenga
3x+51-2x+3=3
Whakaarohia te whārite tuatahi. Hei kimi i te tauaro o 2x-3, kimihia te tauaro o ia taurangi.
x+51+3=3
Pahekotia te 3x me -2x, ka x.
x+54=3
Tāpirihia te 51 ki te 3, ka 54.
x=3-54
Tangohia te 54 mai i ngā taha e rua.
x=-51
Tangohia te 54 i te 3, ka -51.
x=-51 y=4 z=4 a=4 b=4 c=4 d=4
Kua oti te pūnaha te whakatau.
