Tohaina
Kua tāruatia ki te papatopenga
2x-x-\left(-1\right)=5-\left(x-3\right)
Hei kimi i te tauaro o x-1, kimihia te tauaro o ia taurangi.
2x-x+1=5-\left(x-3\right)
Ko te tauaro o -1 ko 1.
x+1=5-\left(x-3\right)
Pahekotia te 2x me -x, ka x.
x+1=5-x-\left(-3\right)
Hei kimi i te tauaro o x-3, kimihia te tauaro o ia taurangi.
x+1=5-x+3
Ko te tauaro o -3 ko 3.
x+1=8-x
Tāpirihia te 5 ki te 3, ka 8.
x+1+x=8
Me tāpiri te x ki ngā taha e rua.
2x+1=8
Pahekotia te x me x, ka 2x.
2x=8-1
Tangohia te 1 mai i ngā taha e rua.
2x=7
Tangohia te 1 i te 8, ka 7.
x=\frac{7}{2}
Whakawehea ngā taha e rua ki te 2.
