Kua tāruatia ki te papatopenga
5\left(x-8\right)=3\left(x-3\right)
Me whakarea ngā taha e rua o te whārite ki te 15, arā, te tauraro pātahi he tino iti rawa te kitea o 3,5.
5x-40=3\left(x-3\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te x-8.
5x-40=3x-9
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te x-3.
5x-40-3x=-9
Tangohia te 3x mai i ngā taha e rua.
2x-40=-9
Pahekotia te 5x me -3x, ka 2x.
2x=-9+40
Me tāpiri te 40 ki ngā taha e rua.
2x=31
Tāpirihia te -9 ki te 40, ka 31.
x=\frac{31}{2}
Whakawehea ngā taha e rua ki te 2.
