Answer:

Find three numbers such that the second number is 3 more than twice the first number,and the third number is four times the first number. The sum of the three numbers is 164.

1st:: x

2nd:: 2x+3

3rd:: 4x

-------------

Equation:

x + 2x+3 + 4x = 164

7x = 161

----

x = 23 (1st)

2x+3 = 49 (2nd)

4x = 92 (3rd)

----------------

Make first number = 'x'

Second number = 3 + 2x

Third number = 4x

Total = 164

So,

x + (3 + 2x) + 4x = 164

x + 3 + 2x + 4x = 164

Collect like terms:

x + 2x + 4x = 164 - 3

7x = 161

x = 23

First number = 23

Second number = 49

Third number = 92
