Final answer:
To add (4x-3) + (2x-4), combine the x terms first to get 6x, then combine the constants to get -7. Answer: 6x - 7.
Step-by-step explanation:
To add (4x-3) + (2x-4), we combine like terms. Combine the x terms first, so 4x + 2x equals 6x. Then combine the constants, so -3 + (-4) equals -7. Therefore, the sum is 6x - 7. Answer choice B is correct.
