Question

13. The sum of two integers is 65. If one of them is -31, find the other.
14. The difference of an integer a and (-6) is 4. Find the value of a.​

Answer 1

Answer:

13) Given,

Sum of two integers = 65

one integer = -31

Therefore,

the other integer = 65 -(-31)

= 65 +31

= 96

14) Given,

Difference of two integers = 4

One integer = a

Other integer = -6

A/Q,

a-(-6) = 4

=> a + 6 = 4

=> a = 4-6

=> a = -2

Therefore value of a is -2

Answer 2

Answer:

Step-by-step explanation:

Q-13

Let The required  number be $x$

Then-

$-31+x =65\\-31-65=-x\\-96=-x\\96=x\\CHECK\\96-31=65\\.: x=96$

Q-14

$a-(-6)=4\\a+6=4\\6+(-4)=-x\\6-4=-x\\2=-x\\-2=x\\ CHECK\\LHS=RHS\\-2-(-6)=4\\-2+6=4\\6-2=4\\4=4\\.: -2=x$
