Question

The sum of two numbers is 45. the smaller number is 15 less than the larger number. what is the number

Answer 1

the smaller number is 15, and the larger number is 30

Explanation:

Sooo, s= smaller number and l=larger number

can be solved two ways (using s)

s + s + 15= 45 subtract 15 on both sides

s + s = 30 add both s, which equals 2s

2s = 30 divide both sides by 2

s = 15

( 15 + 15 + 15 = 45)

(you can solve using l)

l - 15 + l = 45 add 15 on both sides

l + l = 60 add both l, which equals 2l

2l = 60 divide both sides by 2

l = 30

( 30 - 15 + 30 = 45)
