Kua tāruatia ki te papatopenga
2x-7=11\times 5
Me whakarea ngā taha e rua ki te 5.
2x-7=55
Whakareatia te 11 ki te 5, ka 55.
2x=55+7
Me tāpiri te 7 ki ngā taha e rua.
2x=62
Tāpirihia te 55 ki te 7, ka 62.
x=\frac{62}{2}
Whakawehea ngā taha e rua ki te 2.
x=31
Whakawehea te 62 ki te 2, kia riro ko 31.
