Answers:

  • 14x+8-6x-7
  • 4(X+1)+4x-3

Option A and C are correct.

[tex]solution \\ 14x + 8 - 6x - 7 \\ = 14x - 6x + 8 - 7 \\ = 8x + 1 \\ 8(x + 1) \\ = 8 \times x + 8 \times 1 \\ = 8x + 8 \\ 4(x + 1) + 4x - 3 \\ = 4x + 4 + 4x - 3 \\ = 4x + 4x + 4 - 3 \\ = 8x + 1 \\ 8x + 8 - x - 1 \\ = 8x - x + 8 - 1 \\ = 7x + 7[/tex]
