Kua tāruatia ki te papatopenga
-20+6x+\left(-2x+11\right)\left(-3\right)=0
Tē taea kia ōrite te tāupe x ki \frac{11}{2} nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te -2x+11.
-20+6x+6x-33=0
Whakamahia te āhuatanga tohatoha hei whakarea te -2x+11 ki te -3.
-20+12x-33=0
Pahekotia te 6x me 6x, ka 12x.
-53+12x=0
Tangohia te 33 i te -20, ka -53.
12x=53
Me tāpiri te 53 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
x=\frac{53}{12}
Whakawehea ngā taha e rua ki te 12.
