Verify the property x + y = y + x of rational numbers by taking

`x = (-2)/3, y = (-5)/6`

उत्तर

Given, `x = (-2)/3, y = (-5)/6`

Then, LHS = x + y

= `(-2)/3 + (-5)/6`

= `(-2)/3 - 5/6`

= `(-4 - 5)/6`

= `(-9)/6`

And RHS = y + x

= `(-5)/6 + (-2)/3`

= `(-5)/6 - 2/3`

= `(-5 - 4)/6`

= `(-9)/6`

∴ LHS = RHS

Hence, x + y = y + x
