Question

Verify (x+y) =( y + x ) if x =2/3 and y =4/5​

Answer 1

Answer:

Step-by-step explanation:

LHS =

2/3 + 4/5

=5 * 3 + 3* 4 / 15

= 15 + 12/ 15

= 27/15

= 9/5 = LHS..

RHS=

4/5+ 2/3

3*4 + 5*3 / 15

= 12 + 15 / 15

= 27 / 15

= 9/5 = RHS..

THEREFORE, LHS= RHS

HENCE PROVED

Answer 2

x+y=2/3+4/5=10+12/15=22/15

y+x=4/5+2/3=12+20/15=22/15

x+y=22/15

y+x=22/15

x+y=y+x
