Let's see if x=2 is a solution for the inequality 7%2B3x+%3C+7x-2.


7%2B3x+%3C+7x-2 Start with the given inequality.


7%2B3%2A%282%29+%3C+7%2A%282%29-2 Plug in x=2.


13%3C+7%2A%282%29-2 Evaluate and simplify the left side.


13%3C12 Evaluate and simplify the right side.


Since the inequality is not true, this means that x=2 is not a solution.
