Question

The sum of two numbers is 1207 and the difference is 895. What are the two numbers? Show the process.

Answer 1

Hello!!

___________________________________________________

let the number be, x and y.

so,

x+y = 1207....(1)

x-y= 895,

so, x= (895+y)

(895+y) + y = 1207( Putting value of x in (1).

so, 895+ 2y= 1207..

2y= 1207-895..

so , 2y= 312
y= 156.

x= 895+y..( Putting value of y in x)

x= 895+ 156= 1,051

so, y= 156
x= 1051

Answer 2

Let the two numbers are x and y
so according to the question we have,
x+y=1207 ...............(equation no. 1)
x-y=895 .................(equation no. 2)

by adding equation (1) and (2) we get,
2x=2102
or , x=2102÷2=1051

by substraction equation (1) and (2) we get,
2y=312
or, y=312÷2=156

thus the two numbers are
x=1051 and y=156
