1500-5x=1.5\times 300
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te 300-x.
1500-5x=450
Whakareatia te 1.5 ki te 300, ka 450.
-5x=450-1500
Tangohia te 1500 mai i ngā taha e rua.
-5x=-1050
Tangohia te 1500 i te 450, ka -1050.
x=\frac{-1050}{-5}
Whakawehea ngā taha e rua ki te -5.
x=210
Whakawehea te -1050 ki te -5, kia riro ko 210.
