2800+x+1400+2x=14400
Tāpirihia te 1400 ki te 1400, ka 2800.
4200+x+2x=14400
Tāpirihia te 2800 ki te 1400, ka 4200.
4200+3x=14400
Pahekotia te x me 2x, ka 3x.
3x=14400-4200
Tangohia te 4200 mai i ngā taha e rua.
3x=10200
Tangohia te 4200 i te 14400, ka 10200.
x=\frac{10200}{3}
Whakawehea ngā taha e rua ki te 3.
x=3400
Whakawehea te 10200 ki te 3, kia riro ko 3400.
