|7 - x| = 8
3|2x - 5| = 7
2|3x - 4| = 3x + 7
Inequalities such as :
|x| > 4
|5 - x| > 4
3|3x + 5| > 8
2|3x - 4| > 3x + 7
Guides additionally cover equations and inequalities such as :
2|x| = |4 - x|
|x² - 5x| = 6
2|1 - x| - 2|2x + 3| > 3
Examples highlight and simplify algebra that students find hard.
