Step by step explanation:
Now, look at the question.
question: verify x + (y + z) = (x + y) + z
1. x = 3/4, y = 5/6, z = -7/8
=> 3/4+ (5/6 +-7/8) = (3/4 +5/6) + -7/8
=> 3/4 + (20+-21/24) = (9+10/12) + -7/8
=> 3/4+-1/24 = 19/12+-7/8
=> 18+-1/24 = 38+-21/24
=> 17/24 = 17/24
2. x =2/3, y = -5/6, z =-7/9
=> 2/3+(-5/6+-7/9) = (2/3+-5/6) +-7/9
=> 2/3+ (-15+-14/18) = (4+-5/6) + -7/9
=> 2/3+-29/18 = -1/6 +-7/9
=> 12+-29/18 = -3/-4/18
=> -17/18 = -17/18
3. x = 3/5, y = -6/9 , z = 2/10
=> 3/5+ (-6/9+2/10) = (27+ -30/45) +2/1
=> 3/5+(-60+18/90) = (27+-30/45)+2/10
=> 3/5+ -42/90 = -3/45 + 2/10
=> 54+-42/90 = -6+18/90
=> 12/90 = 12/90
4. x = -3/5, y = -7/10, z = -8/15
=> -3/5+ (-7/10+-8/1 (-3/5+-7/10)+-8/15 => -3/5+(-21+-16/30) = (-6+-7/10)+-8/15
=> -3/5+-37/30 = -13/10+-8/15
=> -18+-37/30 = -39+-16/30
=> -55/30 = -55/30
It's all verified. If you have any doubts about this answer, please don't hesitate to ask.
Stay at home, stay safe.
