Kua tāruatia ki te papatopenga
5+18x-36=248
Whakamahia te āhuatanga tohatoha hei whakarea te 18 ki te x-2.
-31+18x=248
Tangohia te 36 i te 5, ka -31.
18x=248+31
Me tāpiri te 31 ki ngā taha e rua.
18x=279
Tāpirihia te 248 ki te 31, ka 279.
x=\frac{279}{18}
Whakawehea ngā taha e rua ki te 18.
x=\frac{31}{2}
Whakahekea te hautanga \frac{279}{18} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 9.
