Compound Inequalities

Attached are 4 files with samples of print "Compound Inequalities", which I have never brailled before and need your help and advice. On Page 41, EXAMPLE 1 shows 2 Methods for solving a compound inequality. Note that Method 1 shows the solution centered between the two inequalities. On Page 44, EXAMPLE 6, section b. shows another inequality which, if alignment is important, would be difficult to braille. Page 47, exercise 51, shows an "or" compound inequality. Page 52, Example 9, shows compound inequalities with comments to the steps. Are there guidelines for alignment and/or format? Thank you.
