Q. Solve for xx.\newline4x+8=x−1 4 x+8=x-1
  1. Subtract xx terms: Subtract xx from both sides to get all xx terms on one side and constants on the other.4x+8−x=x−1−x4x + 8 - x = x - 1 - x3x+8=−13x + 8 = -1
  2. Isolate x term: Subtract 88 from both sides to isolate the term with xx.\newline3x+8−8=−1−83x + 8 - 8 = -1 - 8\newline3x=−93x = -9
  3. Divide to solve xx: Divide both sides by 33 to solve for xx.3x3=−93\frac{3x}{3} = \frac{-9}{3}x=−3x = -3
