Answer 2

Let the numbers be x and y

x > y

x + y = 7 ........... (a)

x - y = 1 ............... (b)

Solving by equating the coefficients method.

Adding (a) and (b), we get

2x = 8 [(+y) and (-y) get cancelled.]

Therefore x = 8 ÷ 2

= 4

Therefore the value of the first number (x) is 4.

The value of second number (y) = 3

x + y = 7

4 + y = 7

y = 7 - 4

y = 3

Answer :- The value of the numbers are 4 and 3 respectively.
