Edits sect 1.1: I did not edit any lines that involved Latex.
Example 1 a: 3/5 needs to be substituted for y in step 2.
Example 1 b: 7/5 needs to be substituted for y in step 2.
After exercise 1, the definition of linear equation is out of order.
example 2: step 1, line 2, negative 8 is missing
step 4, 29 should not be there
after exercise 2: steps numbered incorrectly. Steps should be consolidated. I tried to edit the section the way that I would say it, but the numbering and bulletting is making me crazy.
example 3: should read, … Add m to both sides to get the “variable terms” on the left.
Add 4 to both sides to get the “constants” on the right.
Exercise 5a: H5P is not working correctly. Fractional answer negative 17/5.
Example 7 last sentence should read, … The equation is true when a=4/3, so this is a conditional equation. The solution is a=4/3.
Table after exercise 8 : 1st column isn’t aligned
true for one value of the variable, not one or more values.
solution for conditional should be one value
Example 9: Words in step 3 need to be moved up to line up with the steps, then the check comes after.
In the check, NO “x” in 2nd to last step.
Example 11: In alternative method, correct line 3 and 4 on the left side.
in line 5, should have negative y in red on both sides
Example 12: line 7, ther is an extra “-y-10” on the left side.
Edit that I made:
Took out the redundancy in explanation before Example 1.
In conditional equation section, after exercise 5, conditional equation is true for “one” value of
the variable, not one or more values. Glossary entry for conditional equation may need to be corrected.
Edited the sentence before example 10.
