Answer:
Explanation:
First, you have to simplify and solve for x.
x + 2x + 6 < 50
3x + 6 < 50
3x < 44
x < 14 2/3
x has to be smaller than 14 2/3. The only two numbers in the set that works are {13, 14} replace x with both numbers and solve
14 + (28) + 6 = 50
13 + (26) + 6 < 50
the correct answer is 13
