Tohaina
Kua tāruatia ki te papatopenga
s=2\left(2s-3\right)
Me whakarea ngā taha e rua o te whārite ki te 16, arā, te tauraro pātahi he tino iti rawa te kitea o 16,8.
s=4s-6
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 2s-3.
s-4s=-6
Tangohia te 4s mai i ngā taha e rua.
-3s=-6
Pahekotia te s me -4s, ka -3s.
s=\frac{-6}{-3}
Whakawehea ngā taha e rua ki te -3.
s=2
Whakawehea te -6 ki te -3, kia riro ko 2.
