  1. Distribute and Simplify: First, distribute the 55 and 44 on both sides of the equation.5(x+4)=4(x+4)+295(x+4) = 4(x+4) + 295x+20=4x+16+295x + 20 = 4x + 16 + 29
  2. Combine Like Terms: Now, combine like terms on the right side. 5x+20=4x+455x + 20 = 4x + 45
  3. Isolate Variable: Next, subtract 4x4x from both sides to get xx by itself.\newline5x4x+20=4x4x+455x - 4x + 20 = 4x - 4x + 45\newlinex+20=45x + 20 = 45
  4. Solve for x: Then, subtract 2020 from both sides to solve for x.\newlinex+2020=4520x + 20 - 20 = 45 - 20\newlinex=25x = 25
