4495+225.75x-125.5x=6500
Tangohia te 125.5x mai i ngā taha e rua.
4495+100.25x=6500
Pahekotia te 225.75x me -125.5x, ka 100.25x.
100.25x=6500-4495
Tangohia te 4495 mai i ngā taha e rua.
100.25x=2005
Tangohia te 4495 i te 6500, ka 2005.
x=\frac{2005}{100.25}
Whakawehea ngā taha e rua ki te 100.25.
x=\frac{200500}{10025}
Whakarohaina te \frac{2005}{100.25} mā te whakarea i te taurunga me te tauraro ki te 100.
x=20
Whakawehea te 200500 ki te 10025, kia riro ko 20.
