Tohaina
Kua tāruatia ki te papatopenga
5x+80-2x+1=150
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 40-x.
3x+80+1=150
Pahekotia te 5x me -2x, ka 3x.
3x+81=150
Tāpirihia te 80 ki te 1, ka 81.
3x=150-81
Tangohia te 81 mai i ngā taha e rua.
3x=69
Tangohia te 81 i te 150, ka 69.
x=\frac{69}{3}
Whakawehea ngā taha e rua ki te 3.
x=23
Whakawehea te 69 ki te 3, kia riro ko 23.
