10x+324-12x=300
Whakamahia te āhuatanga tohatoha hei whakarea te 12 ki te 27-x.
-2x+324=300
Pahekotia te 10x me -12x, ka -2x.
-2x=300-324
Tangohia te 324 mai i ngā taha e rua.
-2x=-24
Tangohia te 324 i te 300, ka -24.
x=\frac{-24}{-2}
Whakawehea ngā taha e rua ki te -2.
x=12
Whakawehea te -24 ki te -2, kia riro ko 12.
