Question

(x+y)+2=x+(y+z) for x = -2 , y = 3/5 & z = -4/3 vrify the following​

Answer 1

_______________________

$(x + y) + 2 = x + (y + z)$

Value of x= -2

Value of Y= 3/5

value of z= -4/3

$( -2+ \frac{3}{5} ) + 2 = - 2 + ( \frac{3}{5} + \frac{ - 4}{3} ) \\ \\( \frac{ - 2}{1} + \frac{3}{5} ) + 2 = - 2 + ( \frac{3}{5} + \frac{ - 4}{3} ) \\ \\ ( \frac{ - 10 + 3}{5} ) + 2 = - 2 + ( \frac{9 + ( - 20)}{15} \\ \\ \frac{ - 7}{5} + 2 = - 2 + ( \frac{9 - 20}{15} ) \\ \\ \frac{ - 7}{5} + \frac{2}{1} = - 2 + \frac{ - 11}{15} \\ \\ \frac{ - 7}{5} + \frac{2}{1} = \frac{ - 2}{1} + \frac{ - 11}{15} \\ \\ \frac{ - 7 + 10}{5} = \frac{ - 30 + ( - 11)}{15} \\ \\ \frac{ + 3}{5} = \frac{ - 30 - 11}{15} \\ \\ \frac{3}{5} = \frac{ - 41}{15} \\ \\ \frac{3}{5} \times \frac{ - 41}{15} \\ \\ \frac{ - 41}{25} \\ \\ = - 1.64$
