3x-2x+2=14-5x
Whakamahia te āhuatanga tohatoha hei whakarea te -2 ki te x-1.
x+2=14-5x
Pahekotia te 3x me -2x, ka x.
x+2+5x=14
Me tāpiri te 5x ki ngā taha e rua.
6x+2=14
Pahekotia te x me 5x, ka 6x.
6x=14-2
Tangohia te 2 mai i ngā taha e rua.
6x=12
Tangohia te 2 i te 14, ka 12.
x=\frac{12}{6}
Whakawehea ngā taha e rua ki te 6.
x=2
Whakawehea te 12 ki te 6, kia riro ko 2.
