2x-16+3\left(x+1\right)>3\left(x-2\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te x-8.
2x-16+3x+3>3\left(x-2\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te x+1.
5x-16+3>3\left(x-2\right)
Pahekotia te 2x me 3x, ka 5x.
5x-13>3\left(x-2\right)
Tāpirihia te -16 ki te 3, ka -13.
5x-13>3x-6
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te x-2.
5x-13-3x>-6
Tangohia te 3x mai i ngā taha e rua.
2x-13>-6
Pahekotia te 5x me -3x, ka 2x.
2x>-6+13
Me tāpiri te 13 ki ngā taha e rua.
2x>7
Tāpirihia te -6 ki te 13, ka 7.
x>\frac{7}{2}
Whakawehea ngā taha e rua ki te 2. I te mea he tōrunga te 2, kāore e huri te ahunga koreōrite.
