Question

Verify that -1/2 + [(-4/3) + -3/7] and [(-1/2) + 3/7] + (-4/3) are of same number​

Answer 1

Answer:

LHS:-

LCM=21

-4/3*7/7=-28/21 } =-28+9/21

3/7*3/3=9/21 } =-19/21

-19/21+-1/2

LCM=42

-19/21*2/2=-38/42 }=-38+-21/42

-1/2*21/21=-21/42 }=-59/42

RHS:-

LCM=14

-1/2*7/7=-7/14 }=-7+6/14

3/7*2/2=6/14 }=-1/14

-1/14+-4/3

LCM=42

-1/14*3/3=3/42 }=-3+56/42

-4/3*14/14=-56/42 }=-59/42

LHS=RHS

Answer 2

Step-by-step explanation:

Hiii frnd...

LHS = -1/2 (-4/3 +3/7)

= -1/2 (-28+9/21)

= -1/2(-19/21)

-21-38/42

-59/42

RHS. = (-1/2+3/7) -4/3

=(-7+6/14) -4/3

=-1/14 -4/3

=-3-56/42

-59/42

LHS=RHS

Hope it helps

drop some thnxx plsss.
