Kua tāruatia ki te papatopenga
18\left(-x+30\right)=86-0
Tē taea kia ōrite te tāupe x ki 30 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te -x+30.
-18x+540=86-0
Whakamahia te āhuatanga tohatoha hei whakarea te 18 ki te -x+30.
-18x+540=86
Tangohia te 0 i te 86, ka 86.
-18x=86-540
Tangohia te 540 mai i ngā taha e rua.
-18x=-454
Tangohia te 540 i te 86, ka -454.
x=\frac{-454}{-18}
Whakawehea ngā taha e rua ki te -18.
x=\frac{227}{9}
Whakahekea te hautanga \frac{-454}{-18} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -2.
