How do you know if a value is a solution for an inequality?How is this different from determining if a value is a solution to an equation? If you replace the equal sign of an equation with an inequality sign, is there ever a time when the same value will be a solution to both the equation and the inequality? Write an inequality and provide a value that may or may not be a solution to the inequality.

How is this different from determining if a value is a solution to an equation? If you replace the equal sign of an equation with an inequality sign, is there ever a time when the same value will be a solution to both the equation and the inequality? Write an inequality and provide a value that may or may not be a solution to the inequality.
say
x<12
to check if something is a solution, try it. Like say the number 5
5 < 12 yes, it works
the solution to the equality and inequality can only be the same if the inequality includes the equality. For example:
x</= 12 means x less than or equal to 12
In that case 12 witself would be a solution to both equality and inequality.
However 12 is not less than 12 so it would not be a solution to
x<12
x<12
