Let x be the second number.
Representation:
First number = 2x (twice the second number)
Second number = x
Third number = (2x+x) + 4 (four more than the sum of the first two numbers)
Fourth number = (2x-x) - 3 (three less than the difference of first two numbers)
Total of the four numbers = 92
Equation:
2x + x + (2x+x+4) + (2x-x-3) = 92
2x + x + 3x + 4 + x-3 = 92
Combine the like terms:
2x + x + 3x + x + 4 - 3 = 92
7x +1 = 92
7x = 92-1
7x = 91
7 7
x = 13
The numbers are:
first number = 2x
= 2(13)
= 26
second number = x
= 13
third number = 2x + x + 4
= 2 (13) + 13 + 4
= 26 + 13 + 4
= 43
fourth number = 2x-x-3
= 2(13) - 13 - 3
= 26 - 13- 3
= 10
To check:
26 + 13 + 43 + 10 = 92
92 = 92
