Q. Is u=1 a solution to this equation?16=9−uChoices:(A)yes(B)no
Identify Equation: We have the equation:16=9−uIdentify the equation after substituting u=1.Substitute 1 for u in 16=9−u. Equation: 16=9−1
Substitute and Simplify: Simplify 9−1. 9−1=8
Check Solution: We found: 16=8Is u=1 a solution to the equation 16=9−u?For u=1, the equation becomes 16=8, which is not true.So, u=1 is not a solution to the equation 16=9−u.
