Kua tāruatia ki te papatopenga
2\left(5x-2\right)=3\left(2x+7\right)
Me whakarea ngā taha e rua o te whārite ki te 6, arā, te tauraro pātahi he tino iti rawa te kitea o 3,2.
10x-4=3\left(2x+7\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 5x-2.
10x-4=6x+21
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 2x+7.
10x-4-6x=21
Tangohia te 6x mai i ngā taha e rua.
4x-4=21
Pahekotia te 10x me -6x, ka 4x.
4x=21+4
Me tāpiri te 4 ki ngā taha e rua.
4x=25
Tāpirihia te 21 ki te 4, ka 25.
x=\frac{25}{4}
Whakawehea ngā taha e rua ki te 4.
