Tohaina
Kua tāruatia ki te papatopenga
16-6x-\left(2^{7}-7x\right)=12-\left(5-2x\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 8-3x.
16-6x-\left(128-7x\right)=12-\left(5-2x\right)
Tātaihia te 2 mā te pū o 7, kia riro ko 128.
16-6x-128-\left(-7x\right)=12-\left(5-2x\right)
Hei kimi i te tauaro o 128-7x, kimihia te tauaro o ia taurangi.
16-6x-128+7x=12-\left(5-2x\right)
Ko te tauaro o -7x ko 7x.
-112-6x+7x=12-\left(5-2x\right)
Tangohia te 128 i te 16, ka -112.
-112+x=12-\left(5-2x\right)
Pahekotia te -6x me 7x, ka x.
-112+x=12-5-\left(-2x\right)
Hei kimi i te tauaro o 5-2x, kimihia te tauaro o ia taurangi.
-112+x=12-5+2x
Ko te tauaro o -2x ko 2x.
-112+x=7+2x
Tangohia te 5 i te 12, ka 7.
-112+x-2x=7
Tangohia te 2x mai i ngā taha e rua.
-112-x=7
Pahekotia te x me -2x, ka -x.
-x=7+112
Me tāpiri te 112 ki ngā taha e rua.
-x=119
Tāpirihia te 7 ki te 112, ka 119.
x=-119
Me whakarea ngā taha e rua ki te -1.
