Kua tāruatia ki te papatopenga
15\left(x-0.6\right)=4\times 9
Me whakarea ngā taha e rua ki te 9.
15x-9=4\times 9
Whakamahia te āhuatanga tohatoha hei whakarea te 15 ki te x-0.6.
15x-9=36
Whakareatia te 4 ki te 9, ka 36.
15x=36+9
Me tāpiri te 9 ki ngā taha e rua.
15x=45
Tāpirihia te 36 ki te 9, ka 45.
x=\frac{45}{15}
Whakawehea ngā taha e rua ki te 15.
x=3
Whakawehea te 45 ki te 15, kia riro ko 3.
