Kua tāruatia ki te papatopenga
3x-36=48-2\times 2x
Me whakarea ngā taha e rua o te whārite ki te 6, arā, te tauraro pātahi he tino iti rawa te kitea o 2,3.
3x-36=48-4x
Whakareatia te -2 ki te 2, ka -4.
3x-36+4x=48
Me tāpiri te 4x ki ngā taha e rua.
7x-36=48
Pahekotia te 3x me 4x, ka 7x.
7x=48+36
Me tāpiri te 36 ki ngā taha e rua.
7x=84
Tāpirihia te 48 ki te 36, ka 84.
x=\frac{84}{7}
Whakawehea ngā taha e rua ki te 7.
x=12
Whakawehea te 84 ki te 7, kia riro ko 12.
