Kua tāruatia ki te papatopenga
6x+8+3x-18=15
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te x-6.
9x+8-18=15
Pahekotia te 6x me 3x, ka 9x.
9x-10=15
Tangohia te 18 i te 8, ka -10.
9x=15+10
Me tāpiri te 10 ki ngā taha e rua.
9x=25
Tāpirihia te 15 ki te 10, ka 25.
x=\frac{25}{9}
Whakawehea ngā taha e rua ki te 9.
