Identify Equation: We have the equation 3=4n. Identify the equation after substituting n=4. Substitute 4 for n in 3=4n. Equation: 3=44
Substitute and Simplify: Simplify 44. 44=1
Check Solution: We found: 44=1Is n=4 a solution to the equation 3=4n?For n=4, the equation becomes 1=3, which is not true.So, n=4 is not a solution to the equation 3=4n.
