What is the value of x in the equation 2x + 3 = 7?

• A. 1
• B. 2
• C. 3
• D. 4

Answer: (B)

To find the value of x in the equation 2x + 3 = 7, the first step is to isolate the term containing x. This can be achieved by subtracting 3 from both sides of the equation. Starting with the equation: 2x + 3 = 7 Subtracting 3 from both sides gives: 2x = 7 - 3 This simplifies to: 2x = 4 Next, to solve for x, you need to divide both sides of the equation by 2: x = 4 / 2 This results in: x = 2 Thus, the correct value of x is indeed 2. This is confirmed by substituting x back into the original equation to check if it balances: 2(2) + 3 = 4 + 3 = 7, which holds true. This verification reinforces that the correct answer is 2.

Subtracting 3 from both sides gives:

2x = 7 - 3

This simplifies to:

2x = 4

Next, to solve for x, you need to divide both sides of the equation by 2:

x = 4 / 2

This results in:

x = 2

Thus, the correct value of x is indeed 2. This is confirmed by substituting x back into the original equation to check if it balances:

2(2) + 3 = 4 + 3 = 7, which holds true. This verification reinforces that the correct answer is 2.
