Question

if sum of two number is 10 and difference is 4 than write the numbers ​

Answer 1

let the numbers be X and Y

x+y=10

x-y=4

adding this to equations we get

x=7 y=3

Answer 2

Answer:

let x+y=10

let x-y=4

so, 2x=14

therefore,x=14/2

=7

putting value of x

= 10-x

= 10-7=3

so,number are 7 and 3
