Question

1. The sum of two integers is -12. If one of them is 43. find the other.
​

Answer 1

Answer:

Sum of Two Integers 3D43

One of Them=-27

Let Other =X

AQ

x+(-27)=43

X-27=43

X=43+27

x=70

Other Number=70

CHeck

70+(-27) 70-27=43

Hence ,Other Number=70

Answer 2

Answer:

Step-by-step explanation:

Let's assume the unknown integer is x

The sum of x and 43 is -12

therefore, to present this in an equation form......

x+43=-12

Now, lets transport 43 to the other side of the equal to sign

When it is being transported the sign of +43 will become -43

Now, we have..........

x=-12-43

following the integer addition rule: same sign add, different sign subtract, Put the sign of the greater number

we get........

x=-55
