Identify Substituted Equation: We have the equation 6b=51. Identify the equation after substituting b=7.Substitute 7 for b in 6b=51.Equation: 6×7=51
Substitute and Simplify: Perform the multiplication to simplify 6×7.6×7=42
Check Solution Validity: We found that 6×7=42. Is b=7 a solution to the equation 6b=51?For b=7, the equation becomes 42=51, which is not true.So, b=7 is not a solution to the equation 6b=51.
