-6x+18+4x=3\left(x-4\right)
Whakamahia te āhuatanga tohatoha hei whakarea te -6 ki te x-3.
-2x+18=3\left(x-4\right)
Pahekotia te -6x me 4x, ka -2x.
-2x+18=3x-12
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te x-4.
-2x+18-3x=-12
Tangohia te 3x mai i ngā taha e rua.
-5x+18=-12
Pahekotia te -2x me -3x, ka -5x.
-5x=-12-18
Tangohia te 18 mai i ngā taha e rua.
-5x=-30
Tangohia te 18 i te -12, ka -30.
x=\frac{-30}{-5}
Whakawehea ngā taha e rua ki te -5.
x=6
Whakawehea te -30 ki te -5, kia riro ko 6.
