Tohaina
Kua tāruatia ki te papatopenga
49\times 2=x+1+x-1
Me whakarea ngā taha e rua ki te 2.
98=x+1+x-1
Whakareatia te 49 ki te 2, ka 98.
98=2x+1-1
Pahekotia te x me x, ka 2x.
98=2x
Tangohia te 1 i te 1, ka 0.
2x=98
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
x=\frac{98}{2}
Whakawehea ngā taha e rua ki te 2.
x=49
Whakawehea te 98 ki te 2, kia riro ko 49.
