5 raruraru e ōrite ana ki:
\frac { 3 } { 5 x - 2 } = \frac { - 4 } { ( 4 x + 1 ) }
Tohaina
Kua tāruatia ki te papatopenga
\left(4x+1\right)\times 3=\left(5x-2\right)\left(-4\right)
Tē taea kia ōrite te tāupe x ki tētahi o ngā uara -\frac{1}{4},\frac{2}{5} nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te \left(5x-2\right)\left(4x+1\right), arā, te tauraro pātahi he tino iti rawa te kitea o 5x-2,4x+1.
12x+3=\left(5x-2\right)\left(-4\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 4x+1 ki te 3.
12x+3=-20x+8
Whakamahia te āhuatanga tohatoha hei whakarea te 5x-2 ki te -4.
12x+3+20x=8
Me tāpiri te 20x ki ngā taha e rua.
32x+3=8
Pahekotia te 12x me 20x, ka 32x.
32x=8-3
Tangohia te 3 mai i ngā taha e rua.
32x=5
Tangohia te 3 i te 8, ka 5.
x=\frac{5}{32}
Whakawehea ngā taha e rua ki te 32.
