5x+10+2x-15+2x+5=360
Pahekotia te 3x me 2x, ka 5x.
7x+10-15+2x+5=360
Pahekotia te 5x me 2x, ka 7x.
7x-5+2x+5=360
Tangohia te 15 i te 10, ka -5.
9x-5+5=360
Pahekotia te 7x me 2x, ka 9x.
9x=360
Tāpirihia te -5 ki te 5, ka 0.
x=\frac{360}{9}
Whakawehea ngā taha e rua ki te 9.
x=40
Whakawehea te 360 ki te 9, kia riro ko 40.
