Kua tāruatia ki te papatopenga
18\left(f+35\right)=752+20f
Tē taea kia ōrite te tāupe f ki -35 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te f+35.
18f+630=752+20f
Whakamahia te āhuatanga tohatoha hei whakarea te 18 ki te f+35.
18f+630-20f=752
Tangohia te 20f mai i ngā taha e rua.
-2f+630=752
Pahekotia te 18f me -20f, ka -2f.
-2f=752-630
Tangohia te 630 mai i ngā taha e rua.
-2f=122
Tangohia te 630 i te 752, ka 122.
f=\frac{122}{-2}
Whakawehea ngā taha e rua ki te -2.
f=-61
Whakawehea te 122 ki te -2, kia riro ko -61.
