8t-24+9t<3\left(7+3t\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 8 ki te t-3.
17t-24<3\left(7+3t\right)
Pahekotia te 8t me 9t, ka 17t.
17t-24<21+9t
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 7+3t.
17t-24-9t<21
Tangohia te 9t mai i ngā taha e rua.
8t-24<21
Pahekotia te 17t me -9t, ka 8t.
8t<21+24
Me tāpiri te 24 ki ngā taha e rua.
8t<45
Tāpirihia te 21 ki te 24, ka 45.
t<\frac{45}{8}
Whakawehea ngā taha e rua ki te 8. I te mea he tōrunga te 8, kāore e huri te ahunga koreōrite.
