The equation x + 1 = 2 has one solution.
If you subtract 1 from both sides, you’ll get one value for x:
x + 1 - 1 = 2 - 1
x = 1
Therefore, the equation has ONE solution. This is the only solution that makes the equation true. If you substitute the value of x into the equation, you’ll get:
x + 1 = 2
( 1 ) + 1 = 2
2 = 2
If you try to substitute x with a different value, it will make the equation false. Let’s say the value of x = 4:
x + 1 = 2
( 4 ) + 1 = 2
5 = 2 ← This is a false statement.
Part 2: A value of x that makes the equation true is 1 (which is the solution), which when substituted into the equation and simplified makes the equation turn into a true statement.
Part 3: A value of x that makes the equation false is any real number other than 1, in which when substituted into the equation and simplified makes the equation turn into a false statement (no solutions).
Therefore, the correct answer is the first option: The equation has ONE solution.
