Kua tāruatia ki te papatopenga
27=153x+5\left(12-3x\right)
Whakareatia ngā taha e rua o te whārite ki te 9.
27=153x+60-15x
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te 12-3x.
27=138x+60
Pahekotia te 153x me -15x, ka 138x.
138x+60=27
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
138x=27-60
Tangohia te 60 mai i ngā taha e rua.
138x=-33
Tangohia te 60 i te 27, ka -33.
x=\frac{-33}{138}
Whakawehea ngā taha e rua ki te 138.
x=-\frac{11}{46}
Whakahekea te hautanga \frac{-33}{138} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.
