Q. Solve.\newline3(3x4)=42 3(3 x-4)=42 \newlineAnswer: x= x=
  1. Distribute Terms: Distribute the 33 across the terms inside the parentheses.\newlineWe need to multiply 33 by each term inside the parentheses (3x3x and 4-4).\newlineCalculation: 3×3x=9x3 \times 3x = 9x and 3×4=123 \times -4 = -12\newlineSo, the equation becomes 9x12=429x - 12 = 42.
  2. Add 1212: Add 1212 to both sides of the equation to isolate the term with the variable xx. We want to get xx by itself on one side of the equation, so we need to get rid of the 12-12. Calculation: 9x12+12=42+129x - 12 + 12 = 42 + 12 This simplifies to 9x=549x = 54.
  3. Divide by 99: Divide both sides of the equation by 99 to solve for xx. Now that we have 9x9x, we need to divide by 99 to find the value of xx. Calculation: 9x9=549\frac{9x}{9} = \frac{54}{9} This simplifies to x=6x = 6.
