Answer:
Step-by-step explanation:
y=2x+2
Let x be the 1st number
x + 9 be the second number
Equation:
x + x+9 = 171
Solution:
2x + 9 = 171
2x = 171 - 9
2x = 162
x = 81
x + 9 = 90
81 + 90 = 171
1, 3, 5, 7, 9 are the possible digits
meaning you have 5! possible combinations or 120 combinations
I think it would be 3 because if you divide 18/6=3
