Question

The sum of two numbers is 1. One number is 15 more than the other one. Find the numbers.

Answer 1

x= 8 and y= -7.

Explanation:

Let x be the larger number and y be the smaller number.

x+y= 1 (1)

x-y= 15 (2)

From (2) :

x= y+15 (3)

sub (3) into (1) :

y+15+y= 1

2y= -14

y= -7 (4)

sub (4) into (3) :

x= -7+15

= 8
