a.
To solve: The inequality
a.
Explanation of Solution
Given information:
The inequality
Calculation:
Solve the inequality as follows:
Thus, all real numbers less greater than 3 are solution to the given inequality.
Verification:
Take b = 4 and put in above inequality.
The above inequality is true hence the solution is correct.
b.
To explain: Various other steps that could have been the first step in solving inequality of problem 4.
b.
Explanation of Solution
Given information:
The inequality
Other than subtracting 3n from each side of the inequality one can also start solution by adding 1 on each side of inequality.
Using this approach the solution would have been done as shown below:
As can be seen that solution obtained from both approaches are similar.
