7197+175.75x-150.5x=7500
Tangohia te 150.5x mai i ngā taha e rua.
7197+25.25x=7500
Pahekotia te 175.75x me -150.5x, ka 25.25x.
25.25x=7500-7197
Tangohia te 7197 mai i ngā taha e rua.
25.25x=303
Tangohia te 7197 i te 7500, ka 303.
x=\frac{303}{25.25}
Whakawehea ngā taha e rua ki te 25.25.
x=\frac{30300}{2525}
Whakarohaina te \frac{303}{25.25} mā te whakarea i te taurunga me te tauraro ki te 100.
x=12
Whakawehea te 30300 ki te 2525, kia riro ko 12.
