Kua tāruatia ki te papatopenga
5x-112-x=0
Tangohia te x mai i ngā taha e rua.
4x-112=0
Pahekotia te 5x me -x, ka 4x.
4x=112
Me tāpiri te 112 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
x=\frac{112}{4}
Whakawehea ngā taha e rua ki te 4.
x=28
Whakawehea te 112 ki te 4, kia riro ko 28.
