 Hello and welcome to the session. In this session we will discuss the following question and the question says solve x plus 5 is less than 9, choosing replacement from the set containing the elements minus 1, 0, 1, 2, 3, 4, 5, 6 and graph the solution set. Let's start the solution now. We are given the in equation x plus 5 is less than 9. First we shall solve it. So, we subtract 5 from both the sides. So, we get x plus 5 minus 5 is less than 9 minus 5. Here the inequality remains the same because we have subtracted the same quantity from both the sides. This implies x is less than 4. Now, we are given that the replacement set is this set. So, replacement set is equal to the set containing the elements minus 1, 0, 1, 2, 3, 4, 5, 6. Since after solving the in equation we get x is less than 4 and we have to choose the solution set from the replacement set. So, we choose all the numbers in the replacement set which are less than 4. These numbers are minus 1, 0, 1, 2, 3. Now we will draw the graph for the solution set. For this first we shall draw the number line. Now, this is our number line where the numbers on the right side of 0 are positive numbers and the numbers on the left of 0 are all negative numbers. Now, we shall plot the points that we chose from the replacement set which are less than 4. That is we plot the points minus 1, 0, 1, 2 and 3 on the number line. So, this is the graph for the solution set and graph for the solution set consists of only the points minus 1, 0, 1, 2, 3. With this we end our session. Hope you enjoyed the session.
