Tohaina
Kua tāruatia ki te papatopenga
35z+30=7\left(2\times 5+3\right)
Me whakarea ngā taha e rua o te whārite ki te 35, arā, te tauraro pātahi he tino iti rawa te kitea o 7,5.
35z+30=7\left(10+3\right)
Whakareatia te 2 ki te 5, ka 10.
35z+30=7\times 13
Tāpirihia te 10 ki te 3, ka 13.
35z+30=91
Whakareatia te 7 ki te 13, ka 91.
35z=91-30
Tangohia te 30 mai i ngā taha e rua.
35z=61
Tangohia te 30 i te 91, ka 61.
z=\frac{61}{35}
Whakawehea ngā taha e rua ki te 35.
