Full solution

Q. 150−9x−9x+15=27 150-9 x-9 x+15=27
  1. Combine like terms: Combine like terms on the left side of the equation.\newline150−9x−9x+15150 - 9x - 9x + 15 simplifies to 150+15−18x150 + 15 - 18x, which is 165−18x165 - 18x.
  2. Set equation equal: Set the simplified equation equal to 2727.165−18x=27165 - 18x = 27.
  3. Subtract to isolate: Subtract 165165 from both sides to isolate the term with xx.\newline165−18x−165=27−165165 - 18x - 165 = 27 - 165,\newlinewhich simplifies to −18x=−138-18x = -138.
  4. Divide to solve: Divide both sides by −18-18 to solve for xx.−18x/−18=−138/−18-18x / -18 = -138 / -18,x=7.666x = 7.666.
