Kua tāruatia ki te papatopenga
8x=5\times 8
Me whakarea ngā taha e rua o te whārite ki te 120, arā, te tauraro pātahi he tino iti rawa te kitea o 15,24.
8x=40
Whakareatia te 5 ki te 8, ka 40.
x=\frac{40}{8}
Whakawehea ngā taha e rua ki te 8.
x=5
Whakawehea te 40 ki te 8, kia riro ko 5.
Ngā Tauira
whārite tapawhā
{ x } ^ { 2 } - 4 x - 5 = 0
Āhuahanga
