Question

If sum of two numbers is 14 and di difference is 8 and then find the number find

Answer 1

Answer:

let the two no.s be x and y where x>y

x+y=14

x-y=8

add the above eqs

2x=22

x=22/2

x=11

x+y=14

11+y=14

y=14-11

y=3

hope it helps!

Answer 2

x+y=14
x-y=8=x=8+y

x+y=14
(8+y)+y=14
8+y+y=14
8+2y=14
2y=14-8
2y=6
y=3
So,
x+y=14
x+3=14
x=14-3
x=11
So,
11+3=14
11-3=8
So the answer is
x=11
y=3
