Kua tāruatia ki te papatopenga
4\times 5+4x\times \frac{3}{4}=4\left(-4\right)
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 4x, arā, te tauraro pātahi he tino iti rawa te kitea o x,4.
20+4x\times \frac{3}{4}=4\left(-4\right)
Whakareatia te 4 ki te 5, ka 20.
20+3x=4\left(-4\right)
Me whakakore te 4 me te 4.
20+3x=-16
Whakareatia te 4 ki te -4, ka -16.
3x=-16-20
Tangohia te 20 mai i ngā taha e rua.
3x=-36
Tangohia te 20 i te -16, ka -36.
x=\frac{-36}{3}
Whakawehea ngā taha e rua ki te 3.
x=-12
Whakawehea te -36 ki te 3, kia riro ko -12.
