0.875x=140-x+0.125x
Pahekotia te 1x me -0.125x, ka 0.875x.
0.875x=140-0.875x
Pahekotia te -x me 0.125x, ka -0.875x.
0.875x+0.875x=140
Me tāpiri te 0.875x ki ngā taha e rua.
1.75x=140
Pahekotia te 0.875x me 0.875x, ka 1.75x.
x=\frac{140}{1.75}
Whakawehea ngā taha e rua ki te 1.75.
x=\frac{14000}{175}
Whakarohaina te \frac{140}{1.75} mā te whakarea i te taurunga me te tauraro ki te 100.
x=80
Whakawehea te 14000 ki te 175, kia riro ko 80.
