Question

the sum of two numbers is 50 and their difference is 10

Answer 1

Step-by-step explanation:

let the two numbers be X and Y

equation 1 x+y=50

therefore x= 50-y

equation 2.... x-y=10

-. 50-y-y= 10

-. -2y= -40

-. 2y=40

-. y= 20

now substitute value of y in equation 1

x= 50-y

-. x= 50-20

x=30

therefore x=30&y=20

Answer 2

Answer:

30,20
