Full solution

Q. 5+2x−9=55+ 2x - 9= 5 Find xx
  1. Combine like terms: Simplify the left side of the equation by combining like terms. \newline5−9=−45 - 9 = -4, so we rewrite the equation as: \newline−4+2x=5-4 + 2x = 5
  2. Isolate variable term: Add 44 to both sides of the equation to isolate the term with the variable xx.\newline−4+4+2x=5+4-4 + 4 + 2x = 5 + 4\newlineThis simplifies to:\newline2x=92x = 9
  3. Solve for x: Divide both sides of the equation by 22 to solve for x.\newline2x2=92\frac{2x}{2} = \frac{9}{2}\newlineThis simplifies to:\newlinex=4.5x = 4.5
