What is the solution for x in the equation 2x + 3 = 7?

• A. x = 1
• B. x = 2
• C. x = 3
• D. x = 4

Answer: (B)

To solve the equation 2x + 3 = 7 for x, the first step is to isolate the term containing x. Begin by subtracting 3 from both sides of the equation: 2x + 3 - 3 = 7 - 3 This simplifies to: 2x = 4 Next, to solve for x, divide both sides of the equation by 2: 2x / 2 = 4 / 2 This gives: x = 2 The solution x = 2 indicates that when you substitute 2 back into the original equation, it balances out correctly: 2(2) + 3 = 4 + 3 = 7. Thus, x = 2 is indeed the correct solution to the equation 2x + 3 = 7, confirming the choice given.

To solve the equation 2x + 3 = 7 for x, the first step is to isolate the term containing x. Begin by subtracting 3 from both sides of the equation:

2x + 3 - 3 = 7 - 3

This simplifies to:

2x = 4

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

2x / 2 = 4 / 2

This gives:

x = 2

The solution x = 2 indicates that when you substitute 2 back into the original equation, it balances out correctly:

2(2) + 3 = 4 + 3 = 7.

Thus, x = 2 is indeed the correct solution to the equation 2x + 3 = 7, confirming the choice given.
