Kua tāruatia ki te papatopenga
5x-1500=1.5\times 300
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te x-300.
5x-1500=450
Whakareatia te 1.5 ki te 300, ka 450.
5x=450+1500
Me tāpiri te 1500 ki ngā taha e rua.
5x=1950
Tāpirihia te 450 ki te 1500, ka 1950.
x=\frac{1950}{5}
Whakawehea ngā taha e rua ki te 5.
x=390
Whakawehea te 1950 ki te 5, kia riro ko 390.
