    Answer:

    2×+7 ≠ 3×+1

    Step-by-step explanation:

    Since we know that 2x+7 = 27 and 3x+1 = 28 then we know that 2x+7 ≠ 3x+1.

    27 ≠ 28

    Answer:

    No

    Step-by-step explanation:

    2x + 7 = 27  {Subtract 7 from both sides}

    2x + 7 – 7 = 27- 7

    2x = 20    {divide both sides by 2}

    2x/2 = 20/2

    x = 10

    3x + 1 = 28

    3x = 28- 1

    3x = 27

    3x/3 = 27/3

    x = 9

    So, 2x + 7 ≠ 3x + 1
