Answer:
both answer is a+b=b+a= -65/77
Step-by-step explanation:
a+b
= -3/11+(-4/7)
= -3/11-4/7
=((-3×7)+(-4×11))/11×7
= (-21-44)/77
= -65/77
b+a
= -4/7+(-3/11)
= -4/7-3/11
=((-4×11)+(-3×7))/7×11
= (-44-21)/35
= -65/77
so, a+b=b+a

Answer:Both are same.-23/77=-23/77
Step-by-step explanation: a+b=b+a
=>3/11+-4/7
LHS=RHS
=>LHS=3/11+-4/7
=>LCM of 11 and 7
=>LCM=77
make the denominators same.
3/11x7=21/77 -4/7x11=-44/77
21+- 44/11 =
=>-23/77
RHS=-4/7+3/11
=>LCM of 7 and 11
=>LCM=77
again make the denominators same.
-4/7x11=-44/77 3/11x7=21/77
-44+21/77
=>-23/77
-23/77=-23/77
LHS=RHS
HENCE VERIFIED.
HOPE IT HELPS.IF ANY DOUBT ASK ME!!
