Simplify the expression by combining like terms: 4x + 3x - 2x + 7.

Explanation:
Combining like terms means adding coefficients of terms that share the same variable. Look at the x-terms: 4x, 3x, and -2x. Add the coefficients: 4 + 3 - 2 = 5, giving 5x. The 7 is a constant, with no x, so it stays as +7. Put together, the simplified expression is 5x + 7. The other options would mix or miscount the x-coefficient or change the constant, so they don’t match this correct simplification.
