what to slove here?!
ok... if 1/4 is less than 3+y, then we can write:
1/4 < 3+y
1/4-3 < y or -2 3/4 < y
that is y is more than - 2 3/4

First write the sentence into an equation:
1/4<3+y
then multiply both sides by 4 to get rid of the fraction (remember to distribute the 3 into (3+y):
1<12+3y
subtract 12 from both sides:
-11<3y
divide both sides by 3
-11/3
y>-11/3
y is greater than -11/3

Subtract 3 from both sides. Be sure to write "is less than" as "<" (except without the " marks).

.25<3+y Subtract 3 from both sides.
.25 -3< y
-2.75 < y or y> -2.75
