Kua tāruatia ki te papatopenga
9\left(2x-1\right)=4x+2
Whakareatia ngā taha e rua o te whārite ki te 3.
18x-9=4x+2
Whakamahia te āhuatanga tohatoha hei whakarea te 9 ki te 2x-1.
18x-9-4x=2
Tangohia te 4x mai i ngā taha e rua.
14x-9=2
Pahekotia te 18x me -4x, ka 14x.
14x=2+9
Me tāpiri te 9 ki ngā taha e rua.
14x=11
Tāpirihia te 2 ki te 9, ka 11.
x=\frac{11}{14}
Whakawehea ngā taha e rua ki te 14.
