Simplify the expression 3x + 5 - 2x + 4.

Explanation:
Combine like terms by grouping x-terms together and constants together. The x-terms are 3x and -2x, which add up to (3 - 2)x = x. The constants are 5 and 4, which add up to 9. Put the x-term first and then the constant: x + 9. You can check by plugging in a value for x, say x = 2, to see both sides give 11.
