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
