Question

The sum of two numbers is 64. Twice the smaller number is 10 less than the larger number. What are the numbers?

Answer 1

x = first number
64 - x = second number {sum of two numbers is 64} 
2x = 64 - x - 10 {twice smaller is ten less than larger}
2x = 54 - x {combine like terms}
3x = 54 
x = 18
64 - x = 46 {substituted 18 for x} 

the two numbers are 18 and 46

Answer 2

I  that the two numbers are 18 and 24
