Kua tāruatia ki te papatopenga
6\left(x-2\right)=5\left(x-1\right)
Me whakarea ngā taha e rua o te whārite ki te 30, arā, te tauraro pātahi he tino iti rawa te kitea o 5,6.
6x-12=5\left(x-1\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 6 ki te x-2.
6x-12=5x-5
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te x-1.
6x-12-5x=-5
Tangohia te 5x mai i ngā taha e rua.
x-12=-5
Pahekotia te 6x me -5x, ka x.
x=-5+12
Me tāpiri te 12 ki ngā taha e rua.
x=7
Tāpirihia te -5 ki te 12, ka 7.
