Tohaina
Kua tāruatia ki te papatopenga
15w+4=5\left(3\times 3+1\right)
Me whakarea ngā taha e rua o te whārite ki te 15, arā, te tauraro pātahi he tino iti rawa te kitea o 15,3.
15w+4=5\left(9+1\right)
Whakareatia te 3 ki te 3, ka 9.
15w+4=5\times 10
Tāpirihia te 9 ki te 1, ka 10.
15w+4=50
Whakareatia te 5 ki te 10, ka 50.
15w=50-4
Tangohia te 4 mai i ngā taha e rua.
15w=46
Tangohia te 4 i te 50, ka 46.
w=\frac{46}{15}
Whakawehea ngā taha e rua ki te 15.
