Kua tāruatia ki te papatopenga
10\times 2x-84=63
Me whakarea ngā taha e rua o te whārite ki te 70, arā, te tauraro pātahi he tino iti rawa te kitea o 7,5,10.
20x-84=63
Whakareatia te 10 ki te 2, ka 20.
20x=63+84
Me tāpiri te 84 ki ngā taha e rua.
20x=147
Tāpirihia te 63 ki te 84, ka 147.
x=\frac{147}{20}
Whakawehea ngā taha e rua ki te 20.
