Question

verify x+y=y+x four following values of x and y :x=5/7 and y= -3/2​

Answer 1

Answer:

They are equal,  $-\frac{11}{14}=-\frac{11}{14}$ use substitution

Step-by-step explanation:

Set x and y to their values

$\frac{5}{7}-\frac{3}{2}=-\frac{3}{2}+\frac{5}{7}$

Use fraction addition and subtraction

$\frac{10}{14}-\frac{21}{14}=-\frac{21}{14}+\frac{10}{14}$

Simplify

$-\frac{11}{14}=-\frac{11}{14}$

Therefore it is true
