3x-12=x
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te x-4.
3x-12-x=0
Tangohia te x mai i ngā taha e rua.
2x-12=0
Pahekotia te 3x me -x, ka 2x.
2x=12
Me tāpiri te 12 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
x=\frac{12}{2}
Whakawehea ngā taha e rua ki te 2.
x=6
Whakawehea te 12 ki te 2, kia riro ko 6.
