6x-5-15+2x=180
Pahekotia te 3x me 3x, ka 6x.
6x-20+2x=180
Tangohia te 15 i te -5, ka -20.
8x-20=180
Pahekotia te 6x me 2x, ka 8x.
8x=180+20
Me tāpiri te 20 ki ngā taha e rua.
8x=200
Tāpirihia te 180 ki te 20, ka 200.
x=\frac{200}{8}
Whakawehea ngā taha e rua ki te 8.
x=25
Whakawehea te 200 ki te 8, kia riro ko 25.
