Question

verify (x+y )+ z=( x+y)+z x=2/3,y=-5/6,z=-7/9​

Answer 1

Answer:

Hii..

here is your solution..

Step-by-step explanation:

$(x + y) + z = (x + y) + z \\ gven \: x = \frac{2}{3} \: \: \: \: y = \frac{ - 5}{6} \: \: \: \: and \: z = \frac{ - 7}{9} \\ \\ putting \: the \: value \: of \: given \: equation \: we \: get \\ \\ \frac{2}{3} + \frac{( - 5)}{6} + \frac{( - 7)}{9} \\ = \frac{12 + ( - 15) + ( - 14)}{18} \\ = \frac{12 + ( - 29}{18} \\ = \frac{ - 17}{18}$

hope it helps you..
