6x=18\left(x-10\right)
Pahekotia te 5x me x, ka 6x.
6x=18x-180
Whakamahia te āhuatanga tohatoha hei whakarea te 18 ki te x-10.
6x-18x=-180
Tangohia te 18x mai i ngā taha e rua.
-12x=-180
Pahekotia te 6x me -18x, ka -12x.
x=\frac{-180}{-12}
Whakawehea ngā taha e rua ki te -12.
x=15
Whakawehea te -180 ki te -12, kia riro ko 15.
