Step-by-Step Solution

To solve this problem, let's break it down step-by-step:

  • Step 1: Expand the equation using the distributive property.

Apply the distributive property to each term: 2(43x)+4(2x4)=8(2x) -2(4 - 3x) + 4(2x - 4) = 8(2 - x) 24+(2)(3x)+42x44=828x -2 \cdot 4 + (-2) \cdot (-3x) + 4 \cdot 2x - 4 \cdot 4 = 8 \cdot 2 - 8 \cdot x which simplifies to:

8+6x+8x16=168x -8 + 6x + 8x - 16 = 16 - 8x

  • Step 2: Gather like terms.

Combine xx terms and constants separately: 6x+8x=14xand816=24 6x + 8x = 14x \quad \text{and} \quad -8 - 16 = -24 Thus, the equation becomes: 14x24=168x 14x - 24 = 16 - 8x

  • Step 3: Isolate xx on one side.

Start by adding 8x8x to both sides to bring all terms involving xx to one side: 14x+8x24=16 14x + 8x - 24 = 16 which simplifies to: 22x24=16 22x - 24 = 16

  • Step 4: Solve for xx.

Add 24 to both sides to isolate the term with xx: 22x=16+24 22x = 16 + 24 22x=40 22x = 40 Finally, divide both sides by 22: x=4022=2011 x = \frac{40}{22} = \frac{20}{11}

Therefore, the solution to the equation is 2011\frac{20}{11}.

Answer

2011 \frac{20}{11}
