Question

What two numbers have a sum of 12
and a difference of 8?

Answer 1

Answer:

Two numbers are 10 and 2

Step-by-step explanation:

x + y = 12

x - y = 8

-------------

2x = 20

x = 20/2

x = 10

Keeping the value of x in any of the equation :

x + y = 12

10 + y = 12

y = 12 - 10

y = 2

Answer 2

x+y =12 ( let no. be x and y

x-y=8

subtracting eq

x+y =12

x - y =8

we get 2y =4

y =2

putting value

x+y =12

x +2=12

x =10
