Question

verify that x+y=y+x, x=3/5 y=-7/10

Answer 1

3/5-7/10 = -7/10+3/5
6/10-7/10 = -7/10+6/10
-1/10 = -1/10

HERE IS YOUR ANSWER↓↓↓↓↓↓↓↓↓↓.

To verify :- x + y = y +x 
where ,
                x = $\frac{3}{5}$
                y = $\frac{-7}{10}$
then, 
3/5 + (-7/10) = (-7/10 ) + 3/5 
Takinf L.C.M. of Denominator ,
$\frac{3*2 - 7}{10}$ = $\frac{-7 + 3*2}{10}$
then,
$\frac{-1}{10}$ = $\frac{-1}{10}$.
Hence Proved ,
