Identify Substituted Equation: We have the equation 6v=216. Identify the equation after substituting v=12. Substitute 12 for v in 6v=216. Equation: 6×12=216
Substitute and Simplify: Perform the multiplication to simplify 6×12.6×12=72
Check Solution Validity: We found that 6×12=72. Is v=12 a solution to the equation 6v=216? For v=12, the equation becomes 72=216, which is not true. So, v=12 is not a solution to the equation 6v=216.
