Full solution

Q. Subtract.\newline(3r+9)−(2r+6)(3r + 9) - (2r + 6)
  1. Distribute negative sign: First, distribute the negative sign across the second expression.\newline(3r+9)−(2r+6)=3r+9−2r−6(3r + 9) - (2r + 6) = 3r + 9 - 2r - 6
  2. Combine like terms: Next, combine like terms.\newline3r−2r+9−6=r+33r - 2r + 9 - 6 = r + 3
