Tohaina
Kua tāruatia ki te papatopenga
8x+8-4x=0
Whakaarohia te whārite tuatahi. Tangohia te 4x mai i ngā taha e rua.
4x+8=0
Pahekotia te 8x me -4x, ka 4x.
4x=-8
Tangohia te 8 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-8}{4}
Whakawehea ngā taha e rua ki te 4.
x=-2
Whakawehea te -8 ki te 4, kia riro ko -2.
x=-2 y=24 z=24 a=24
Kua oti te pūnaha te whakatau.
