Question

the sum of two numbers is 2, their difference is 8. what are the two numbers. (it says one will be negative)

Answer 1

Answer:

The numbers are 5 and -3...

Step-by-step explanation:

Let the first number be x and the second number be y...

Now, x + y = 2

and x - y = 8

Now add both the equations, we get.

2x = 10

x = 5

so, y = 2 - x

y = 2 - 5

y = -3

Answer 2

Answer:

the two numbers are 5 and -3

Step-by-step explanation:

let the two numbers be x and y

x + y=2 -----------(1)

x - y=8 -------------(2)

(1)+(2)

2x=10

x=5

x=5 in (1)

5+y=2

y=-3

the two numbers are 5 and -3
