Question

find the sum of two integers whose sum is -12 and difference is -2​

Answer 1

Step-by-step explanation:

Let those 2 numbers be x, y

Then x+y=12 and x-y=2

we can add these two equations

= x+y=12

x-y=2

= 2x=14

X=14/2=7

x+y=12

7+y=12

y=12–7=5

So x= 7 and y=5

Answer 2

Answer:

5 and 7

Step-by-step explanation:

sum of two numbers = x+y =-12__________(1)

and diff. is = x-y= -2 __________(2)

add eqn (2) and (1)

x+y=-12

x-y=-2

________

2x=-14

x = -7

and y = -5
