Tohaina
Kua tāruatia ki te papatopenga
18x-42=6x-6
Whakamahia te āhuatanga tohatoha hei whakarea te 6 ki te 3x-7.
18x-42-6x=-6
Tangohia te 6x mai i ngā taha e rua.
12x-42=-6
Pahekotia te 18x me -6x, ka 12x.
12x=-6+42
Me tāpiri te 42 ki ngā taha e rua.
12x=36
Tāpirihia te -6 ki te 42, ka 36.
x=\frac{36}{12}
Whakawehea ngā taha e rua ki te 12.
x=3
Whakawehea te 36 ki te 12, kia riro ko 3.
