Question

5. Verify that x + y = y + x for each of the following:
​

Answer 1

$\huge \bold{\mid {\underline { \overline \red{AnSwer}}}} \mid$

first let x and y are 1 and 2 respectively

• LHS = x + y
• RHS = y + x

then,

LHS = 1 + 2 = 3

RHS = 2 + 1 = 3

• LHS = RHS

hence, verified!

x + y = y + x
