Question

the sum of two integers is - 70. if one of the integer is -30, find the other.​

Answer 1

We start the question like this-
Let the other integer be x.
x+(-30)=-70
x-30=-70
x=30-70
x=-40
Hence, the other integer is -40

Answer 2

Sum of two integer = -70

If one of the integer = -30

then other be x

So

Their sum = -70

= -30 + x = -70

= x = -70 + 30

x = - 40

Now verification as we know their sum = -70

So now

-30 - 40 = -70

Finally Other number = -40
