Kua tāruatia ki te papatopenga
x+56=3\left(16+x\right)
Tē taea kia ōrite te tāupe x ki -56 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te 3\left(x+56\right), arā, te tauraro pātahi he tino iti rawa te kitea o 3,56+x.
x+56=48+3x
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 16+x.
x+56-3x=48
Tangohia te 3x mai i ngā taha e rua.
-2x+56=48
Pahekotia te x me -3x, ka -2x.
-2x=48-56
Tangohia te 56 mai i ngā taha e rua.
-2x=-8
Tangohia te 56 i te 48, ka -8.
x=\frac{-8}{-2}
Whakawehea ngā taha e rua ki te -2.
x=4
Whakawehea te -8 ki te -2, kia riro ko 4.
