How do you check whether #x=3# is a solution to #2x-5<7#?
To check whether x = 3 is a solution to 2x - 5 < 7, you substitute 3 in for x and simplify the solution. If the statement is true then it is a solution. If the statement is false then it is not a solution.
Here is the check:
2x - 5 < 7
2(3) - 5 < 7
6 - 5 < 7
1 < 7 (This reads one is less than seven)
This statement is true and therefore x = 3 is one of the solutions of 2x - 5 < 7.
Since it is an inequality, there are many numbers that are solutions to this inequality, you can solve the inequality.
Therefore any number less than 6 will be a solution to 2x - 5 < 7.
