4x-4-\left(x-5\right)=10
Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te x-1.
4x-4-x-\left(-5\right)=10
Hei kimi i te tauaro o x-5, kimihia te tauaro o ia taurangi.
4x-4-x+5=10
Ko te tauaro o -5 ko 5.
3x-4+5=10
Pahekotia te 4x me -x, ka 3x.
3x+1=10
Tāpirihia te -4 ki te 5, ka 1.
3x=10-1
Tangohia te 1 mai i ngā taha e rua.
3x=9
Tangohia te 1 i te 10, ka 9.
x=\frac{9}{3}
Whakawehea ngā taha e rua ki te 3.
x=3
Whakawehea te 9 ki te 3, kia riro ko 3.
