the sum of two numbers is 38 . the smaller number is 22 less than the larger number. what are the numbers?

larger number:
smaller number:

larger number: 30

smaller number: 8

larger number= x

smaller number= b

x+b=38

Also, b=x-22

Substitute x-22 for b.

x+ (x-22) =38

2x = 60

x =30, this b= (30-22) =8

3x + 4y -25 =0 represents the amount of change sianna should recieve
