Kua tāruatia ki te papatopenga
4+2\times 5x=7
Me whakarea ngā taha e rua o te whārite ki te 12, arā, te tauraro pātahi he tino iti rawa te kitea o 3,6,12.
4+10x=7
Whakareatia te 2 ki te 5, ka 10.
10x=7-4
Tangohia te 4 mai i ngā taha e rua.
10x=3
Tangohia te 4 i te 7, ka 3.
x=\frac{3}{10}
Whakawehea ngā taha e rua ki te 10.
