3x-\left(-2\right)-\left(-5x\right)=x+2
Hei kimi i te tauaro o -2-5x, kimihia te tauaro o ia taurangi.
3x+2-\left(-5x\right)=x+2
Ko te tauaro o -2 ko 2.
3x+2+5x=x+2
Ko te tauaro o -5x ko 5x.
8x+2=x+2
Pahekotia te 3x me 5x, ka 8x.
8x+2-x=2
Tangohia te x mai i ngā taha e rua.
7x+2=2
Pahekotia te 8x me -x, ka 7x.
7x=2-2
Tangohia te 2 mai i ngā taha e rua.
7x=0
Tangohia te 2 i te 2, ka 0.
x=0
He ōrite te hua o ngā tau e rua ki 0 ina 0 tētahi o rāua te iti rawa. Tātemea kāore te 7 e ōrite ki 0, me ōrite pū te x ki 0.
