Full solution

Q. The sum of a number and 1818 is 29-29\newlineThe equation is \square . (Do not simplify.)
  1. Define Unknown Number: Let's denote the unknown number as xx. The problem states that the sum of this number and 1818 is 29-29. We can write this as an equation:\newlinex+18=29x + 18 = -29\newlineThis is the equation we are looking for.
  2. Solve Equation: Now, we need to check if the equation is correct by substituting a value for xx that would make the equation true. If we subtract 1818 from both sides of the equation, we should find the value of xx.x+1818=2918x + 18 - 18 = -29 - 18x=47x = -47
  3. Verify Solution: To verify our solution, we substitute x=47x = -47 back into the original equation to see if the left side equals the right side.\newline47+18=29-47 + 18 = -29\newline29=29-29 = -29\newlineThis shows that our equation is correct.
