Ok so I'm a little confused about your question. But there is such thing as a one solution equation no solution equations and infinity solution equation here are some examples.
One solution equation: Consistent, Independent. EX. X=4
What three consecutive integers have a sum of 246? Which means that the first number is 81, the second number is 81 + 1 and the third number is 81 + 2. Therefore, three consecutive integers that add up to 246 are 81, 82, and 83.
