16x-16=12x+36
Whakamahia te āhuatanga tohatoha hei whakarea te 16 ki te x-1.
16x-16-12x=36
Tangohia te 12x mai i ngā taha e rua.
4x-16=36
Pahekotia te 16x me -12x, ka 4x.
4x=36+16
Me tāpiri te 16 ki ngā taha e rua.
4x=52
Tāpirihia te 36 ki te 16, ka 52.
x=\frac{52}{4}
Whakawehea ngā taha e rua ki te 4.
x=13
Whakawehea te 52 ki te 4, kia riro ko 13.
