Question

The sum of two numbers is 57. The larger number is thrice the smaller number decreased by 3. What are the numbers?

Answer 1

Answer:

the 2 numbers are 15 and 42

Step-by-step explanation:

let a and b be the 2 numbers

given that a+b = 57  ------- (1)

also, b = 3a - 3

substitute the value of b in (1)

=> a + 3a-3  = 57

=> 4a = 57+3

=> a = 60/4

=> a = 15

substitute a=15 in (1), we get

15 + b = 57

=> b = 57-15

=> b = 42

=> the 2 numbers are 15 and 42
