5x-10=2-2x+10x-30
Whakamahia te āhuatanga tohatoha hei whakarea te 10 ki te x-3.
5x-10=2+8x-30
Pahekotia te -2x me 10x, ka 8x.
5x-10=-28+8x
Tangohia te 30 i te 2, ka -28.
5x-10-8x=-28
Tangohia te 8x mai i ngā taha e rua.
-3x-10=-28
Pahekotia te 5x me -8x, ka -3x.
-3x=-28+10
Me tāpiri te 10 ki ngā taha e rua.
-3x=-18
Tāpirihia te -28 ki te 10, ka -18.
x=\frac{-18}{-3}
Whakawehea ngā taha e rua ki te -3.
x=6
Whakawehea te -18 ki te -3, kia riro ko 6.
