8x+4-10x\leq 4x-74
Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te 2x+1.
-2x+4\leq 4x-74
Pahekotia te 8x me -10x, ka -2x.
-2x+4-4x\leq -74
Tangohia te 4x mai i ngā taha e rua.
-6x+4\leq -74
Pahekotia te -2x me -4x, ka -6x.
-6x\leq -74-4
Tangohia te 4 mai i ngā taha e rua.
-6x\leq -78
Tangohia te 4 i te -74, ka -78.
x\geq \frac{-78}{-6}
Whakawehea ngā taha e rua ki te -6. I te mea he tōraro a -6, ka huri te ahunga koreōrite.
x\geq 13
Whakawehea te -78 ki te -6, kia riro ko 13.
