4x-200-6x=-1000
Tangohia te 6x mai i ngā taha e rua.
-2x-200=-1000
Pahekotia te 4x me -6x, ka -2x.
-2x=-1000+200
Me tāpiri te 200 ki ngā taha e rua.
-2x=-800
Tāpirihia te -1000 ki te 200, ka -800.
x=\frac{-800}{-2}
Whakawehea ngā taha e rua ki te -2.
x=400
Whakawehea te -800 ki te -2, kia riro ko 400.
