Kua tāruatia ki te papatopenga
23x+0=15x-16
Whakareatia te 0 ki te 8, ka 0.
23x=15x-16
Ko te tau i tāpiria he kore ka hua koia tonu.
23x-15x=-16
Tangohia te 15x mai i ngā taha e rua.
8x=-16
Pahekotia te 23x me -15x, ka 8x.
x=\frac{-16}{8}
Whakawehea ngā taha e rua ki te 8.
x=-2
Whakawehea te -16 ki te 8, kia riro ko -2.
