Discuss the following:
I. Given a 1-variable linear equation 10z-4=86. Explain the techniques, and show the steps used for solving this equation. Check if the solution is correct.
II. Using the same 1-variable linear equation in I above, change the linear equation to a linear inequality (Use either < or >). Explain the techniques, and show the steps used for manipulating the linear inequality. Check if the solution is correct.
III. Interpret the solution to the linear equation and inequality, and explain the differences in results. Explain how the obtained value is a solution for the inequality.
