    The answer is - 7 because you subtract the opposite of 8 and - 6-8 is adding two negatives then - 14 divides by 2 equals - 7 which equals x (-7=x)

    2x + 8 = - 6

    Subtract 8 from both sides

    2x = - 14

    Divide 2 on both sides

    Final Answer: x = - 7

    Check: 2x + 8 = - 6

    Substitute x for - 7

    2 (-7) + 8=-6

    Multiply - 7 by 2

    -14+8 = - 6

    Add

    Final Answer: - 6 = - 6

    This proves that x is - 7
