Question 222391
24-7y&#8804;11y-14 Treat the <= signs like a normal = sign for grouping terms.
-7y-11y<=-14-24
-18y<=-38
y>=-38/-18 ( Note this is one exception when dividing by a negative value the < sign changes to the > sign.
y>=19/9 ans.
Proof:
Let y=20/9
24-7*20/9<=11*20/9-14
24-140/9<=220/9-14
(9*24-140)/9<=(220-9*14)/9
(216-140)/9<=(220-126)/9
76/9<=94/9
