There will be a homework quiz on Monday. You may use your textbook and your notes to answer the questions. The questions will be taken from the class notes, the homework, and the blog.
Answers for today's homework:
10a. x = -(11/15)
10b. x = 8
10c. no solution
Homework for Monday 9-26: page 37; 11a, 11b, 11c, 11d, 12a
Hint for 12c: Try to get a common denominator or try to clear the denominators (get rid of fractions)
After you simplify an equation, you may get to a statement that doesn't make sense. If you have done the proper undoing, balancing, and operating equally on both sides, and you get a statement that is false,
such as 0 = 5, it means there is no solution to the equation. There is nothing you can put in for x that will make the equation true.
If you simplify an equation and end up with a statement that is always true regardless of x, such as
5 = 5 or 2x = 2x, means the equation has infinite solutions. No matter what you put in for x, the statement will be true.
