-10+6x=3\left(4x-2\right)
Tangohia te 12 i te 2, ka -10.
-10+6x=12x-6
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 4x-2.
-10+6x-12x=-6
Tangohia te 12x mai i ngā taha e rua.
-10-6x=-6
Pahekotia te 6x me -12x, ka -6x.
-6x=-6+10
Me tāpiri te 10 ki ngā taha e rua.
-6x=4
Tāpirihia te -6 ki te 10, ka 4.
x=\frac{4}{-6}
