1500-5x=15\times 300
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te 300-x.
1500-5x=4500
Whakareatia te 15 ki te 300, ka 4500.
-5x=4500-1500
Tangohia te 1500 mai i ngā taha e rua.
-5x=3000
Tangohia te 1500 i te 4500, ka 3000.
x=\frac{3000}{-5}
Whakawehea ngā taha e rua ki te -5.
x=-600
Whakawehea te 3000 ki te -5, kia riro ko -600.
