5x+10-3x\leq 4+2x+3\left(x-1\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te x+2.
2x+10\leq 4+2x+3\left(x-1\right)
Pahekotia te 5x me -3x, ka 2x.
2x+10\leq 4+2x+3x-3
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te x-1.
2x+10\leq 4+5x-3
Pahekotia te 2x me 3x, ka 5x.
2x+10\leq 1+5x
Tangohia te 3 i te 4, ka 1.
2x+10-5x\leq 1
Tangohia te 5x mai i ngā taha e rua.
-3x+10\leq 1
Pahekotia te 2x me -5x, ka -3x.
-3x\leq 1-10
Tangohia te 10 mai i ngā taha e rua.
-3x\leq -9
Tangohia te 10 i te 1, ka -9.
x\geq \frac{-9}{-3}
Whakawehea ngā taha e rua ki te -3. I te mea he tōraro a -3, ka huri te ahunga koreōrite.
x\geq 3
Whakawehea te -9 ki te -3, kia riro ko 3.
