−4(3x+10)−2=54

1 answer

To solve the equation \(-4(3x + 10) - 2 = 54\), follow these steps:

  1. Distribute \(-4\) to the terms inside the parentheses: \[ -4 \cdot 3x - 4 \cdot 10 - 2 = 54 \] This simplifies to: \[ -12x - 40 - 2 = 54 \]

  2. Combine the constants on the left side: \[ -12x - 42 = 54 \]

  3. Next, add \(42\) to both sides of the equation to isolate the term with \(x\): \[ -12x - 42 + 42 = 54 + 42 \] This simplifies to: \[ -12x = 96 \]

  4. Finally, divide both sides by \(-12\) to solve for \(x\): \[ x = \frac{96}{-12} \] This simplifies to: \[ x = -8 \]

Thus, the solution to the equation is: \[ \boxed{-8} \]
