2500-5x+2x=2050
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te 500-x.
2500-3x=2050
Pahekotia te -5x me 2x, ka -3x.
-3x=2050-2500
Tangohia te 2500 mai i ngā taha e rua.
-3x=-450
Tangohia te 2500 i te 2050, ka -450.
x=\frac{-450}{-3}
Whakawehea ngā taha e rua ki te -3.
x=150
Whakawehea te -450 ki te -3, kia riro ko 150.
