Whakaoti mō p
p = \frac{79}{40} = 1\frac{39}{40} = 1.975
Tohaina
Kua tāruatia ki te papatopenga
20\left(2p+1\right)-85=14
Whakareatia te 4 ki te 5, ka 20.
40p+20-85=14
Whakamahia te āhuatanga tohatoha hei whakarea te 20 ki te 2p+1.
40p-65=14
Tangohia te 85 i te 20, ka -65.
40p=14+65
Me tāpiri te 65 ki ngā taha e rua.
40p=79
Tāpirihia te 14 ki te 65, ka 79.
p=\frac{79}{40}
Whakawehea ngā taha e rua ki te 40.
