Q. Is s=−78s = -78 a solution to this equation?\newlines78=−2\frac{s}{78} = -2\newlineChoices:\newline(A)yes\newline(B)no
  1. Substitute and Evaluate: We have the equation s78=−2\frac{s}{78} = -2. Let's substitute s=−78s = -78 into the equation to see if it satisfies the equation.\newlineSubstitute −78-78 for ss in s78=−2\frac{s}{78} = -2.\newlineEquation after substitution: (−78)78=−2\frac{(-78)}{78} = -2
  2. Simplify Division: Simplify (−78)/78(-78)/78.(−78)/78(-78)/78 simplifies to −1-1 because −78-78 divided by 7878 equals −1-1.
  3. Compare Results: Compare the simplified result with the right side of the equation.\newlineWe found that (−78)/78=−1(-78)/78 = -1, but the equation requires that s/78=−2s/78 = -2.\newlineSince −1-1 does not equal −2-2, s=−78s = -78 is not a solution to the equation s/78=−2s/78 = -2.
