Question

The sum of two numbers is 72. Their difference is 48. What are the numbers? *​

Answer 1

Answer:

60 and 12

Step-by-step explanation:

Let the two numbers be x and y

ATQ,

$x + y = 72 \\ x - y = 48$

Adding both the equations

$x + x + y - y = 72 + 48 \\ 2x = 120 \\ x = 60$

Substituting the value of x in the first equation

$(60) + y = 72 \\ y = 72 - 60 \\ y = 12$

x = 60; y = 12

Hence the two numbers are 60 and 12
