Full solution

Q. Is w=78w = 78 a solution to this equation?\newline0=w780 = \frac{w}{78}\newlineChoices:\newline(A)yes\newline(B)no
  1. Substitute value in equation: We are given w=78w = 78. Let's substitute the value for ww in the equation 0=w780 = \frac{w}{78}.\newline0=w780 = \frac{w}{78}\newlineSubstitute ww with 7878.\newline0=78780 = \frac{78}{78}
  2. Calculate division: Calculate 7878 divided by 7878. \newline7878=1\frac{78}{78} = 1
  3. Compare values and solution: The equation 0=w780 = \frac{w}{78} now becomes 0=10 = 1 after the substitution.\newlineCompare the values on both sides of the equation.\newlineIs w=78w = 78 a solution to the equation 0=w780 = \frac{w}{78}?\newlineAfter substituting w=78w = 78, we see that the left side of the equation is 00, and the right side is 11, which are not equal:\newline010 \neq 1\newlineThus, w=78w = 78 is not a solution to the equation 0=w780 = \frac{w}{78}.
