Question

a=(-3)/(11) and b= (-4)= (7) find if a+b =b+a​

Answer 1

Answer:

-63/11 = -63/11

Step-by-step explanation:

Given a= (-3)/11   and b= -4/7

to find a+b = b+a

LHS a+b       =               RHS b+a

-3/11   +   -4/7                 -4/7 + -3/11

-21-44 /77                       -44- 21/11

-63/77             =        -63/11  Hence proved
