2x-5x+10=-3+5x-27
Whakamahia te āhuatanga tohatoha hei whakarea te -5 ki te x-2.
-3x+10=-3+5x-27
Pahekotia te 2x me -5x, ka -3x.
-3x+10=-30+5x
Tangohia te 27 i te -3, ka -30.
-3x+10-5x=-30
Tangohia te 5x mai i ngā taha e rua.
-8x+10=-30
Pahekotia te -3x me -5x, ka -8x.
-8x=-30-10
Tangohia te 10 mai i ngā taha e rua.
-8x=-40
Tangohia te 10 i te -30, ka -40.
x=\frac{-40}{-8}
Whakawehea ngā taha e rua ki te -8.
x=5
Whakawehea te -40 ki te -8, kia riro ko 5.
