5 raruraru e ōrite ana ki:
\frac { x } { 3 } - \frac { 8 } { 7 } \leq 3 x + \frac { 2 } { 3 }
Tohaina
Kua tāruatia ki te papatopenga
7x-24\leq 63x+14
Me whakarea ngā taha e rua o te whārite ki te 21, arā, te tauraro pātahi he tino iti rawa te kitea o 3,7. Nō te mea he >0 te 21, ka noho pērā tonu te ahunga koreōrite.
7x-24-63x\leq 14
Tangohia te 63x mai i ngā taha e rua.
-56x-24\leq 14
Pahekotia te 7x me -63x, ka -56x.
-56x\leq 14+24
Me tāpiri te 24 ki ngā taha e rua.
-56x\leq 38
Tāpirihia te 14 ki te 24, ka 38.
x\geq \frac{38}{-56}
Whakawehea ngā taha e rua ki te -56. Nō te mea he <0 te -56, ka hurihia te ahunga koreōrite.
x\geq -\frac{19}{28}
Whakahekea te hautanga \frac{38}{-56} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
