Full solution

Q. x+7=−12 x+7=-12
  1. Question Prompt: question_prompt: What is the value of xx in the equation x+7=−12x+7=-12?
  2. Subtract 77: Subtract 77 from both sides to isolate xx; x+7−7=−12−7x+7-7=-12-7
  3. Simplify Equation: Simplify the equation; x=−19x=-19
  4. Check Solution: Check the solution by substituting xx back into the original equation; (−19)+7(-19)+7 should equal −12-12
  5. Perform Check: Perform the check; −19+7=−12-19+7=-12, which is true, so the solution is correct
