Q. Solve for x x.\newline−3(−3x−3)−5x+3=40 -3(-3 x-3)-5 x+3=40
  1. Distribute and simplify: First, distribute the −3-3 inside the parentheses.−3(−3x)−3(−3)−5x+3=40-3(-3x) - 3(-3) - 5x + 3 = 409x+9−5x+3=409x + 9 - 5x + 3 = 40
  2. Combine like terms: Combine like terms on the left side of the equation.\newline9x−5x+9+3=409x - 5x + 9 + 3 = 40\newline4x+12=404x + 12 = 40
  3. Isolate x term: Subtract 1212 from both sides to isolate the term with xx.\newline4x+12−12=40−124x + 12 - 12 = 40 - 12\newline4x=284x = 28
  4. Solve for x: Divide both sides by 44 to solve for x.\newline4x4=284\frac{4x}{4} = \frac{28}{4}\newlinex=7x = 7
