8x+32=10x-16
Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te 2x+8.
8x+32-10x=-16
Tangohia te 10x mai i ngā taha e rua.
-2x+32=-16
Pahekotia te 8x me -10x, ka -2x.
-2x=-16-32
Tangohia te 32 mai i ngā taha e rua.
-2x=-48
Tangohia te 32 i te -16, ka -48.
x=\frac{-48}{-2}
Whakawehea ngā taha e rua ki te -2.
x=24
Whakawehea te -48 ki te -2, kia riro ko 24.
