288x+75600-378x=6280
Whakamahia te āhuatanga tohatoha hei whakarea te 378 ki te 200-x.
-90x+75600=6280
Pahekotia te 288x me -378x, ka -90x.
-90x=6280-75600
Tangohia te 75600 mai i ngā taha e rua.
-90x=-69320
Tangohia te 75600 i te 6280, ka -69320.
x=\frac{-69320}{-90}
Whakawehea ngā taha e rua ki te -90.
x=\frac{6932}{9}
Whakahekea te hautanga \frac{-69320}{-90} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -10.
