Answer 1

Answer:

mark me brainliest

Step-by-step explanation:

i. let the other no be x

-5 + x = -1

x = -1 -[-5]

x = -1 + 5

x = 4

ii. if u mean what should be added to the i. ans that is 4 then  do it the same way

4 + x = 16

x = 16 - 4 = 12

iii. let the no be x

4 - x = 48

x = 48 + 4

x = 52

iv. sum of 3, 2 and 1 = 6

4 - 6 = -2
