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