Answer 2

Answer:

-74/35 should be added to 5/7 to get -7/5

Step-by-step explanation:

Let x be the number

5/7 + x = -7/5

x = -7/5 - 5/7

x = -7×7/5×7 - 5×5/7×5

x = - 49/35 - 25/35

x = - 74/35

Check ⇒

5/7 + x = -7/5

x = - 74/35

5/7 + (-74/35) = -7/5

5/7 - 74/35 = -7/5

5×5/7×5 - 74×1/35×1 = -7/5

25/35 - 74/35 = -7/5

-49/35 = -7/5

-7/5 = -7/5

L.H.S = R.H.S

Hence, verified.

The answer is correct.
