Answer:
Step-by-step explanation:
First, we take left hand side x+ (y + z) and put the value of x, y, z
2/3+(-5/6+7/9) = 2/3+ {(-45+42)/54}
= 2/3 + (-3/54) = 2/3 – 1/18 = (36-3)/54
= 33/54 = 11/18
Then, we take right hand side (x +y) +z
Put the value of x, y, z.
= (2/3-5/6) + 7/9 = {(4-5)/6} + 7/9
=-1/6 + 7/9 = (-3+14)/18 = 11/18
Hence x + (y+ z) = (x + y) +z
