What did you try to do?
Alice
revise a little bit the chapter of equations and inequalities...
in this case you have to solve two inequalities
-2less or equal(3x+1)/4 and (3x+1)/4 less thar equal to 11
in both cases apply cross multiplication to get rid off the denominator...
try it is is easy
we can help you but do not expect us to solve your homework...show us your working...
Its not homework I'm studying for an exam and this work wasn't included in the textbook as I was overseas for 2 weeks and my teacher can't stay back to explain and during class he is busy teaching new content so I need to learn this stuff again but have no one to teach me so....
