4x-4=2\left(x+8\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te x-1.
4x-4=2x+16
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te x+8.
4x-4-2x=16
Tangohia te 2x mai i ngā taha e rua.
2x-4=16
Pahekotia te 4x me -2x, ka 2x.
2x=16+4
Me tāpiri te 4 ki ngā taha e rua.
2x=20
Tāpirihia te 16 ki te 4, ka 20.
x=\frac{20}{2}
Whakawehea ngā taha e rua ki te 2.
x=10
Whakawehea te 20 ki te 2, kia riro ko 10.
