Full solution

Q. x+55=6x2\frac{x+5}{5}=\frac{6}{x-2} Find `x`
  1. Cross-multiply fractions: Cross-multiply to eliminate the fractions.\newline(x+5)×(x2)=5×6(x + 5) \times (x - 2) = 5 \times 6
  2. Distribute and simplify: Distribute to simplify the left side of the equation. \newlinex(x2)+5(x2)=30x(x - 2) + 5(x - 2) = 30\newlinex22x+5x10=30x^2 - 2x + 5x - 10 = 30
  3. Combine like terms: Combine like terms on the left side of the equation. x2+3x10=30x^2 + 3x - 10 = 30
  4. Move terms and set to zero: Move all terms to one side to set the equation to zero.\newlinex2+3x1030=0x^2 + 3x - 10 - 30 = 0\newlinex2+3x40=0x^2 + 3x - 40 = 0
  5. Factor quadratic equation: Factor the quadratic equation.\newline(x+8)(x5)=0(x + 8)(x - 5) = 0
  6. Set factors equal and solve: Set each factor equal to zero and solve for xx.x+8=0x + 8 = 0 or x5=0x - 5 = 0x=8x = -8 or x=5x = 5
  7. Check solutions: Check the solutions in the original equation to ensure they do not create a division by zero or other inconsistencies.\newlineFor x=8x = -8:\newline(8+5)/5=6/(82)(-8 + 5)/5 = 6/(-8 - 2)\newline3/5=6/10-3/5 = 6/-10\newline3/5=3/5-3/5 = -3/5 (This is consistent, so x=8x = -8 is a valid solution.)\newlineFor x=5x = 5:\newline(5+5)/5=6/(52)(5 + 5)/5 = 6/(5 - 2)\newline10/5=6/310/5 = 6/3\newline2=22 = 2 (This is consistent, so x=5x = 5 is also a valid solution.)
