Kua tāruatia ki te papatopenga
3\left(2x-5\right)=2\left(x+1\right)
Me whakarea ngā taha e rua o te whārite ki te 12, arā, te tauraro pātahi he tino iti rawa te kitea o 4,6.
6x-15=2\left(x+1\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 2x-5.
6x-15=2x+2
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te x+1.
6x-15-2x=2
Tangohia te 2x mai i ngā taha e rua.
4x-15=2
Pahekotia te 6x me -2x, ka 4x.
4x=2+15
Me tāpiri te 15 ki ngā taha e rua.
4x=17
Tāpirihia te 2 ki te 15, ka 17.
x=\frac{17}{4}
Whakawehea ngā taha e rua ki te 4.
