Q. Find xx:\newline5x−9+(−5)=255x-9+(-5)=25
  1. Combine like terms: Combine like terms on the left side of the equation.\newline5x−9−5=255x - 9 - 5 = 25\newline5x−14=255x - 14 = 25
  2. Add 1414 to isolate: Add 1414 to both sides of the equation to isolate the term with the variable xx.5x−14+14=25+145x - 14 + 14 = 25 + 145x=395x = 39
  3. Divide by 55: Divide both sides of the equation by 55 to solve for xx.5x5=395\frac{5x}{5} = \frac{39}{5}x=7.8x = 7.8
