30+0.13x-0.15x=0
Tangohia te 0.15x mai i ngā taha e rua.
30-0.02x=0
Pahekotia te 0.13x me -0.15x, ka -0.02x.
-0.02x=-30
Tangohia te 30 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-30}{-0.02}
Whakawehea ngā taha e rua ki te -0.02.
x=\frac{-3000}{-2}
Whakarohaina te \frac{-30}{-0.02} mā te whakarea i te taurunga me te tauraro ki te 100.
x=1500
Whakawehea te -3000 ki te -2, kia riro ko 1500.
