Step-by-step solution

To solve the equation 63×(x+4)5=x32 \frac{6-3\times(x+4)}{5} = \frac{x-3}{2} , we follow these steps:

  • Step 1: Eliminate Fractions
    Multiply both sides by the least common multiple of the denominators, which is 10: 10×(63×(x+4)5)=10×(x32) 10 \times \left(\frac{6-3\times(x+4)}{5}\right) = 10 \times \left(\frac{x-3}{2}\right)
  • Step 2: Simplify
    This simplifies to: 2×(63×(x+4))=5×(x3) 2 \times (6 - 3 \times (x+4)) = 5 \times (x - 3)
  • Step 3: Distribute
    Distribute on both sides: 2×62×3×(x+4)=5x15 2 \times 6 - 2 \times 3 \times (x+4) = 5x - 15
  • Step 4: Simplify the distribution
    Simplifying gives: 126×(x+4)=5x15 12 - 6 \times (x+4) = 5x - 15
  • Step 5: Further distribute and simplify: 126x24=5x15 12 - 6x - 24 = 5x - 15 Combine like terms: 6x12=5x15 -6x - 12 = 5x - 15
  • Step 6: Solve for x x
    Add 6x 6x to both sides: 12=11x15 -12 = 11x - 15 Add 15 to both sides: 3=11x 3 = 11x Divide by 11: x=311 x = \frac{3}{11}

Therefore, the solution to the problem is x=311 x = \frac{3}{11} .
