What value of x makes this equation true?

2 (3x - 8) = 2 (7x + 2)

1 answer

To solve the equation \(2 (3x - 8) = 2 (7x + 2)\), we can start by simplifying both sides.

  1. Distribute the 2 on both sides: \[ 2 \cdot (3x - 8) = 6x - 16 \] \[ 2 \cdot (7x + 2) = 14x + 4 \]

    So, the equation now looks like this: \[ 6x - 16 = 14x + 4 \]

  2. Next, we want to isolate \(x\). Let's start by getting all terms involving \(x\) on one side and constant terms on the other side. We can subtract \(6x\) from both sides: \[ -16 = 14x - 6x + 4 \] This simplifies to: \[ -16 = 8x + 4 \]

  3. Now, subtract 4 from both sides to isolate the term with \(x\): \[ -16 - 4 = 8x \] Which gives us: \[ -20 = 8x \]

  4. Finally, divide both sides by 8 to solve for \(x\): \[ x = \frac{-20}{8} = \frac{-5}{2} \]

Thus, the value of \(x\) that makes the original equation true is: \[ \boxed{-\frac{5}{2}} \]
