Question

Verify X + Y = y + X for the following values of X and Y
1.x=5/7,y=-3/2 verify X + Y = 2y + X for the following values of X and Y
1.x=5/7,y=-3/2

Answer 1

Answer:

(1). x+y=y+x

5/7+3/2=3/2+5/7

10+21/14=21+10/14

31/14=31/14

rhs=lhs

(2). x+y=2y+x

5/7+3/2=3+5/7

10+21/14=21+5

31/14≠26

Answer 2

Answer. LHS- x+y

=

5/1+3/2

=5 multiply by 2+3 multiply by 1

=10+3/2

=13/2 answer.

RHS ,y+X

=3/2+5/1

=3+5/2

=3multiply 1 + 5multiply by 2

=3+10/2

=13/2 ans
