Question

The difference of two numbers is 18 and their sum is 66 find the two numbers

Answer 1

Step-by-step explanation:

Difference of two no. =18

Sum=66

let the two numbers be x And y

so, x-y=18

x+y=66

x + y = 66

x = 66 - y

(66 - y) - y = 18

66 - 2y = 18

-2y = 18 - 66

-2y = -42

-2y/-2 = -42/-2

y = 24

Now that you have y, plug that into the first equation and solve for x.

x + 24 = 66

x = 66 - 24

x = 42

Then plug your two answers into both original equations to verify.

x + y = 66

42 + 24 = 66

66 = 66 check

x - y = 18

42 - 24 = 18

18 = 18 check........
