9x-36-5x=x-12
Whakamahia te āhuatanga tohatoha hei whakarea te 9 ki te x-4.
4x-36=x-12
Pahekotia te 9x me -5x, ka 4x.
4x-36-x=-12
Tangohia te x mai i ngā taha e rua.
3x-36=-12
Pahekotia te 4x me -x, ka 3x.
3x=-12+36
Me tāpiri te 36 ki ngā taha e rua.
3x=24
Tāpirihia te -12 ki te 36, ka 24.
x=\frac{24}{3}
Whakawehea ngā taha e rua ki te 3.
x=8
Whakawehea te 24 ki te 3, kia riro ko 8.
