7x-14=3x-2
Whakamahia te āhuatanga tohatoha hei whakarea te 7 ki te x-2.
7x-14-3x=-2
Tangohia te 3x mai i ngā taha e rua.
4x-14=-2
Pahekotia te 7x me -3x, ka 4x.
4x=-2+14
Me tāpiri te 14 ki ngā taha e rua.
4x=12
Tāpirihia te -2 ki te 14, ka 12.
x=\frac{12}{4}
Whakawehea ngā taha e rua ki te 4.
x=3
Whakawehea te 12 ki te 4, kia riro ko 3.
