The sum of two numbers is 27 and their difference is 7.what is the bigger number....

x = 17

Step-by-step explanation:

Let 'x' be the bigger number

'y' be the smaller number

x + y = 27

or x = 27 - y --equation1

x - y = 7 --equation 2

Substitute equation 1 to 2

27 - y - y = 7

-y-y = 7 - 27

-2y = -20

y = 10

Substitute it to equation 1

x = 27 - y

x = 27 - 10

x = 17
