Full solution

Q. 2x+2−4=42x+2-4=4
  1. Combine like terms: Simplify the equation by combining like terms on the left side. \newline2x+2−42x + 2 - 4 can be simplified to 2x−22x - 2 because 2−42 - 4 equals −2-2.\newlineSo, the simplified equation is 2x−2=42x - 2 = 4.
  2. Add to isolate xx: Add 22 to both sides of the equation to isolate the term with the variable xx.2x−2+2=4+22x - 2 + 2 = 4 + 2This simplifies to 2x=62x = 6.
  3. Divide to solve for x: Divide both sides of the equation by 22 to solve for x.\newline2x2=62\frac{2x}{2} = \frac{6}{2}\newlineThis simplifies to x=3x = 3.
