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.
