Question

Given that 2×+7=27 and 3×+1=28, does 2×+7=3×+1? explain
​

Answer 1

2×+7 ≠ 3×+1

Explanation:

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

27 ≠ 28

Answer 2

No

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
