given the inequality:
-9 < 4x + 3 < 27
we are to solve for x
we will have to solve the innquality seperately.
recall, if a
so,
-9 < 4x + 3
subtract 3 from bothe sides
-9 -3 < 4x + 3 - 3
-12 < 4x
divide both sides by 4
-12/4 < 4x/4
-3 < x
so lets solve for the other part.
4x + 3 < 27
subtract 3 from both sides
4x + 3 - 3 < 27 - 3
the +3 and -3 cancels out on the left hand side
4x < 27 - 3
4x < 24
divide both sides by 4
4x/4 < 24/4
x < 24/4
x < 6
therefore the combining the two:
-3(with no spaces).
