5 raruraru e ōrite ana ki:
\frac { 7 - 9 y } { 2 } + 14 \leq \frac { 6 y - 10 } { 3 } - 19 y
Tohaina
Kua tāruatia ki te papatopenga
3\left(7-9y\right)+84\leq 2\left(6y-10\right)-114y
Me whakarea ngā taha e rua o te whārite ki te 6, arā, te tauraro pātahi he tino iti rawa te kitea o 2,3. I te mea he tōrunga te 6, kāore e huri te ahunga koreōrite.
21-27y+84\leq 2\left(6y-10\right)-114y
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 7-9y.
105-27y\leq 2\left(6y-10\right)-114y
Tāpirihia te 21 ki te 84, ka 105.
105-27y\leq 12y-20-114y
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 6y-10.
105-27y\leq -102y-20
Pahekotia te 12y me -114y, ka -102y.
105-27y+102y\leq -20
Me tāpiri te 102y ki ngā taha e rua.
105+75y\leq -20
Pahekotia te -27y me 102y, ka 75y.
75y\leq -20-105
Tangohia te 105 mai i ngā taha e rua.
75y\leq -125
Tangohia te 105 i te -20, ka -125.
y\leq \frac{-125}{75}
Whakawehea ngā taha e rua ki te 75. I te mea he tōrunga te 75, kāore e huri te ahunga koreōrite.
y\leq -\frac{5}{3}
Whakahekea te hautanga \frac{-125}{75} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 25.
