6x + 5

2x + 1

2x - 1

6x - 1

Answer explanation

To combine like terms in 4x - 3 + 2 - 2x, first combine the x terms: 4x - 2x = 2x. Then combine the constants: -3 + 2 = -1. Thus, the final expression is 2x - 1, which matches the correct answer.

3x – 2

11x – 2

11x + 8

11x – 8

Answer explanation

To simplify (7x + 3) + (4x - 5), combine like terms: 7x + 4x = 11x and 3 - 5 = -2. Thus, the expression simplifies to 11x - 2, which is the correct answer.

Answer explanation

To simplify (7x + 14) - (9x - 1), distribute the negative: 7x + 14 - 9x + 1. Combine like terms: (7x - 9x) + (14 + 1) = -2x + 15. Thus, the correct answer is –2x + 15.
