Separate the number 53 into three parts so that the second number is 3 less than the first number and the third number is twice the first number. give the value of the second number.

First number = x
second number = x-3
third number = 2x

x + x-3 + 2x = 53
4x -3 =53
4x -3+3 =53+3
4x = 56
4x/4 = 56/4
x = 14

first number = 14
second number = 14-3
second number = 11

third number = 2x
third number = 2(14)
third number = 28

14 + 11 +28 = 53
53=53
