16x-128=4x-8
Whakamahia te āhuatanga tohatoha hei whakarea te 16 ki te x-8.
16x-128-4x=-8
Tangohia te 4x mai i ngā taha e rua.
12x-128=-8
Pahekotia te 16x me -4x, ka 12x.
12x=-8+128
Me tāpiri te 128 ki ngā taha e rua.
12x=120
Tāpirihia te -8 ki te 128, ka 120.
x=\frac{120}{12}
Whakawehea ngā taha e rua ki te 12.
x=10
Whakawehea te 120 ki te 12, kia riro ko 10.
