Solve for x : −4(2x−11)+7=19 .

1 answer

To solve the equation \(-4(2x - 11) + 7 = 19\), follow these steps:

  1. Distribute \(-4\) across the terms in the parentheses: \[ -4 \cdot 2x + -4 \cdot -11 = -8x + 44. \] So the equation becomes: \[ -8x + 44 + 7 = 19. \]

  2. Combine the constants on the left side: \[ 44 + 7 = 51. \] Therefore, the equation simplifies to: \[ -8x + 51 = 19. \]

  3. Subtract 51 from both sides: \[ -8x + 51 - 51 = 19 - 51, \] resulting in: \[ -8x = -32. \]

  4. Now, divide both sides by \(-8\): \[ x = \frac{-32}{-8} = 4. \]

Thus, the solution is: \[ \boxed{4}. \]
