equations

8-11x/4 less than or equal to13
x greater than or equal to -4

To solve this problem, we need to solve for x.  The first step to do this, you have to multiply everything in the equation by 4.  You have to get rid of the fraction to start.  Then when you multiply everything by 4, the 4's cancel on one side and the other you just multiply and get 8-11x less than or equal to 52.  Now you have to subtract the 8 on both sides.  Once you do this, you get -11x less than or equal to 44.  The next step to solving this problem, you have to divide -11 on both sides also.  When you divide a number on both sides, you have to flip the sign that is in the middle of the problem.  When you do this, you get x greater than or equal to -4.  This is your answer to the problem.
