x-31800-0.006x=0
Tangohia te 0.006x mai i ngā taha e rua.
0.994x-31800=0
Pahekotia te x me -0.006x, ka 0.994x.
0.994x=31800
Me tāpiri te 31800 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
x=\frac{31800}{0.994}
Whakawehea ngā taha e rua ki te 0.994.
x=\frac{31800000}{994}
Whakarohaina te \frac{31800}{0.994} mā te whakarea i te taurunga me te tauraro ki te 1000.
x=\frac{15900000}{497}
Whakahekea te hautanga \frac{31800000}{994} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
