5 raruraru e ōrite ana ki:
\frac { 1 } { 9 } + \frac { 1 } { x } = \frac { 1 } { 6 }
Tohaina
Kua tāruatia ki te papatopenga
18x\times \frac{1}{9}+18=3x
Tē taea kia ōrite te tāupe x ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te 18x, arā, te tauraro pātahi he tino iti rawa te kitea o 9,x,6.
\frac{18}{9}x+18=3x
Whakareatia te 18 ki te \frac{1}{9}, ka \frac{18}{9}.
2x+18=3x
Whakawehea te 18 ki te 9, kia riro ko 2.
2x+18-3x=0
Tangohia te 3x mai i ngā taha e rua.
-x+18=0
Pahekotia te 2x me -3x, ka -x.
-x=-18
Tangohia te 18 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=18
Me whakarea ngā taha e rua ki te -1.
Ngā Tauira
whārite tapawhā
{ x } ^ { 2 } - 4 x - 5 = 0
