Based on the information, the values will be 3+3+1 = 7
Let the number be represented by x.
Since we are to get a doubles plus one fact for the sum of 7, this can be represented in an equation and solved as follows:
= (2 × x) + 1 = 7
2x + 1 = 7
Collect like terms
2x = 7 - 1
2x = 6.
x = 6/2
x = 3
Therefore, the values will be 3+3+1 = 7
