Q. Is n=4 a solution to this equation?5n=38Choices:(A) yes(B) no
Identify Substituted Equation: We have the equation 5n=38. Identify the equation after substituting n=4.Substitute 4 for n in 5n=38.Equation: 5×4=38
Perform Multiplication: Perform the multiplication to simplify 5×4.5×4=20
Compare Results: Compare the result from Step 2 with the right side of the equation.We found that 5×4=20, but the equation requires that 5n should equal 38.Since 20 does not equal 38, n=4 is not a solution to the equation 5n=38.
