Question

verify that x + (y+z)=(x+y)+z for the following values of x,y and z. iv) x= -3 by 5, y= -7 by 10 , z= -8 by 15​

Answer 1

Step-by-step explanation:

$x + (y + z) = - \frac{3}{5} + ( - \frac{7}{10} - \frac{8}{15} ) = - \frac{11}{6} \\ (x + y) + z = ( - \frac{3}{5} - \frac{7}{10} ) - \frac{8}{15} = - \frac{11}{6}$

it's done.
