Question

The sum of two numbers is 22 the difference is 6 . Find the number

Answer 1

x+y= 22

x-y= 6

2x = 28 then x = 28/2= 14

14+ y = 22

y= 22-14=8

Answer 2

Step-by-step explanation:

let the number be x and y,then

x+y=22...equ(1)

x -y=6

or ,x=6+y ..equ (2)

substituting the value of x in equ 1

(6+y) +y=22

or,6+2y =22

or,2y=22-6

• or ,y=16÷2
• or ,y=8

putting the value of y in equ (2)

• x=6+8
• x=14
