A number is 12 more than the other.Find the numbers if their sum is 48

 

Answer:

Smaller number = 18

Bigger number = 30

Step-by-step explanation:

Let x be the number

x + (x + 12) = 48

2x + 12 = 48

2x = 48 - 12

2x = 36

2x/2 = 36/2

x = 18

18 is the smaller number.

x + 12

18 + 12 = 30

30 is the bigger number.

Checking:

x + (x + 12) = 48

12 + (18 + 12) = 48

12 + 30 = 48

48 = 48
