Kua tāruatia ki te papatopenga
4x-\left(x-2\right)=24-8x
Me whakarea ngā taha e rua o te whārite ki te 12, arā, te tauraro pātahi he tino iti rawa te kitea o 3,12.
4x-x-\left(-2\right)=24-8x
Hei kimi i te tauaro o x-2, kimihia te tauaro o ia taurangi.
4x-x+2=24-8x
Ko te tauaro o -2 ko 2.
3x+2=24-8x
Pahekotia te 4x me -x, ka 3x.
3x+2+8x=24
Me tāpiri te 8x ki ngā taha e rua.
11x+2=24
Pahekotia te 3x me 8x, ka 11x.
11x=24-2
Tangohia te 2 mai i ngā taha e rua.
11x=22
Tangohia te 2 i te 24, ka 22.
x=\frac{22}{11}
Whakawehea ngā taha e rua ki te 11.
x=2
Whakawehea te 22 ki te 11, kia riro ko 2.
