Full solution

Q. Solve the equation.\newline73x+6+13=5x+2 \frac{7}{3 x+6}+\frac{1}{3}=\frac{5}{x+2}
  1. Find Common Denominator: First, we need to find a common denominator for the fractions on the left side of the equation to combine them. The common denominator for (3x+6)(3x+6) and 33 is 3(3x+6)3(3x+6).
  2. Eliminate Denominators: Now, we multiply each fraction by the common denominator to eliminate the denominators. This gives us:\newline(7)(3)+(1)(3x+6)=(5)(3)(3x+6)/(x+2)(7)(3) + (1)(3x+6) = (5)(3)(3x+6)/(x+2)
  3. Distribute Numerators: Next, we distribute the numerators across the terms inside the parentheses: 21+3x+6=15(3x+6)/(x+2)21 + 3x + 6 = 15(3x+6)/(x+2)
  4. Combine Like Terms: Combine like terms on the left side of the equation: 3x+27=15(3x+6)x+23x + 27 = \frac{15(3x+6)}{x+2}
  5. Get Rid of Fraction: Now, we need to get rid of the fraction on the right side of the equation by multiplying both sides by (x+2)(x+2):\newline(3x+27)(x+2)=15(3x+6)(3x + 27)(x+2) = 15(3x+6)
  6. Distribute and Combine: Distribute (x+2)(x+2) on the left side and 1515 on the right side:\newline3x2+6x+54x+108=45x+903x^2 + 6x + 54x + 108 = 45x + 90
  7. Set Equation to Zero: Combine like terms on the left side: 3x2+60x+108=45x+903x^2 + 60x + 108 = 45x + 90
  8. Factor Quadratic Equation: Subtract 45x45x and 9090 from both sides to set the equation to zero:\newline3x2+15x+18=03x^2 + 15x + 18 = 0
  9. Factor Quadratic Equation: Subtract 45x45x and 9090 from both sides to set the equation to zero:\newline3x2+15x+18=03x^2 + 15x + 18 = 0 Now, we need to factor the quadratic equation:\newline(3x+3)(x+6)=0(3x + 3)(x + 6) = 0
