Find Smaller Number

[nycmathguy]

Two positive numbers are in the ratio 3:4. The sum of thrice the first number and twice the second is 68. Find the smaller number.

Let me see.

3(3x) + 2(4x) = 68

9x + 8x = 68

17x = 68

x = 68/17

x = 4

3x = 3(4) = 12

4x = 4(4) = 16

The smaller number is 12.
