hoblos · Answer

is 3/4 x + 3 = 3x/4  +3  or   3/4x  +3

accessdenied · Answer

test each point in both inequalities;
 if both inequalities are true for those values, then that is the solution.
 otherwise, it must not be a solution.

Ex) for (0,8)
 8 < 3/4 (0) + 3
 8 < 0 + 3
 8 < 3      false!

The first inequality does not work, so it is not a solution.
