Tohaina
Kua tāruatia ki te papatopenga
10x+10+80=180
Whakamahia te āhuatanga tohatoha hei whakarea te 10 ki te x+1.
10x+90=180
Tāpirihia te 10 ki te 80, ka 90.
10x=180-90
Tangohia te 90 mai i ngā taha e rua.
10x=90
Tangohia te 90 i te 180, ka 90.
x=\frac{90}{10}
Whakawehea ngā taha e rua ki te 10.
x=9
Whakawehea te 90 ki te 10, kia riro ko 9.
