Q. Is v=7v = 7 a solution to this equation?\newline21=63v21 = \frac{63}{v}\newlineChoices:\newline(A) yes\newline(B) no
  1. Identify Equation: We have the equation 21=63v21 = \frac{63}{v}. Identify the equation after substituting v=7v = 7. Substitute 77 for vv in 21=63v21 = \frac{63}{v}. Equation after substitution: 21=63721 = \frac{63}{7}
  2. Simplify Division: Simplify 63/763/7. 63/7=963 / 7 = 9
  3. Check Solution: We found that 637\frac{63}{7} equals 99.\newlineIs v=7v = 7 a solution to the equation 21=63v21 = \frac{63}{v}?\newlineFor v=7v=7, the equation becomes 21=921 = 9, which is not true.\newlineSo, v=7v = 7 is not a solution to the equation 21=63v21 = \frac{63}{v}.
