Q. 4n30=2(2n+15)4n-30=2(2n+15)\newlineWhich of the following best describes the solutions to the equation shown?\newlineChoose 11 answer:\newline(A) There is exactly one solution, n=0n=0.\newline(B) There is exactly one solution, n=154n=-\frac{15}{4}.\newline(C) There are no solutions.\newline(D) There are infinitely many solutions.
  1. Expand and Simplify: First, we need to simplify and solve the equation. Let's start by expanding the right side of the equation.\newline4n30=2(2n+15)4n - 30 = 2(2n + 15)\newline4n30=4n+304n - 30 = 4n + 30
  2. Isolate Constant Terms: Now, we subtract 4n4n from both sides to isolate the constant terms.\newline4n4n30=4n4n+304n - 4n - 30 = 4n - 4n + 30\newline030=0+300 - 30 = 0 + 30
  3. Combine Like Terms: Simplify the equation by combining like terms.\newline30=30-30 = 30
  4. Identify Contradiction: We see that 3030-30 \neq 30, which indicates that there is a contradiction. This means there are no solutions to the equation.
