Full solution

Q. Solve the equation. Check your solution.−3p+3=12-3p+3=12
  1. Isolate variable term: Isolate the term containing the variable pp. To do this, we need to subtract 33 from both sides of the equation to get −3p-3p on one side. −3p+3−3=12−3-3p + 3 - 3 = 12 - 3 This simplifies to: −3p=9-3p = 9
  2. Solve for p: Solve for p by dividing both sides of the equation by -3＂).\(\newline\$-3p / -3 = 9 / -3\)\(\newline\)This simplifies to:\(\newline\)\(p = -3\)
  3. Check solution: Check the solution by substituting \(p = -3\) back into the original equation.\(\newline\)\(-3(-3) + 3 = 12\)\(\newline\)\(9 + 3 = 12\)\(\newline\)\(12 = 12\)\(\newline\)The left side of the equation equals the right side, which means our solution is correct.
