Math Problem Statement

Solve the equation: x + 1/2(6x - 4) = 8

Solution

Let's analyze the problem presented in the image. The equation given is:

x+12(6x4)=8x + \frac{1}{2}(6x - 4) = 8

There is a table showing the steps taken to solve the equation, but the justifications are missing. The possible answers refer to various properties such as the distributive property, combining like terms, addition and subtraction properties of equality, and the division property of equality.

Step-by-Step Explanation:

  1. Step 1: x+3x2=8x + 3x - 2 = 8 Here, the distributive property is used. The 12(6x4)\frac{1}{2}(6x - 4) is expanded to 3x23x - 2.

  2. Step 2: 4x2=84x - 2 = 8 Combining like terms: x+3x=4xx + 3x = 4x.

  3. Step 3: 4x=104x = 10 Addition property of equality is used to add 2 to both sides.

  4. Step 4: x=2.5x = 2.5 Division property of equality is used to divide both sides by 4.

Correct Answer:

The correct answer should have these justifications:

  1. Distributive Property
  2. Combine Like Terms
  3. Addition Property of Equality
  4. Division Property of Equality

Thus, the correct answer is Option 1.
