Tohaina
Kua tāruatia ki te papatopenga
20u-15=4\left(7\times 5+3\right)
Me whakarea ngā taha e rua o te whārite ki te 20, arā, te tauraro pātahi he tino iti rawa te kitea o 4,5.
20u-15=4\left(35+3\right)
Whakareatia te 7 ki te 5, ka 35.
20u-15=4\times 38
Tāpirihia te 35 ki te 3, ka 38.
20u-15=152
Whakareatia te 4 ki te 38, ka 152.
20u=152+15
Me tāpiri te 15 ki ngā taha e rua.
20u=167
Tāpirihia te 152 ki te 15, ka 167.
u=\frac{167}{20}
Whakawehea ngā taha e rua ki te 20.
