Q. Is d=11 a solution to this equation?2d=79Choices:(A) yes(B) no
Identify Equation: We have the equation 2d=79. Identify the equation after substituting d=11.Substitute 11 for d in 2d=79.Equation after substitution: 2×11=79
Substitute and Identify: Perform the multiplication to simplify 2×11.Calculation: 2×11=22
Perform Multiplication: Compare the result of the multiplication with the right side of the equation.We found that 2×11=22, but the equation requires 2d=79.Since 22 does not equal 79, d=11 is not a solution to the equation 2d=79.
