Kua tāruatia ki te papatopenga
\frac{1}{1}x-4=4-x
Whakareatia ngā taha e rua o te whārite ki te 2.
1x-4=4-x
Ka whakawehea he tau ki te tahi, hua ai ko ia anō.
1x-4+x=4
Me tāpiri te x ki ngā taha e rua.
2x-4=4
Pahekotia te 1x me x, ka 2x.
2x=4+4
Me tāpiri te 4 ki ngā taha e rua.
2x=8
Tāpirihia te 4 ki te 4, ka 8.
x=\frac{8}{2}
Whakawehea ngā taha e rua ki te 2.
x=4
Whakawehea te 8 ki te 2, kia riro ko 4.
