Problem

A football game was played between two teams, the Cougars and the Panthers. The two teams scored a total of $34$ points, and the Cougars won by a margin of $14$ points. How many points did the Panthers score?

$\textbf{(A) } 10\qquad \textbf{(B) } 14\qquad \textbf{(C) } 17\qquad \textbf{(D) } 20\qquad \textbf{(E) } 24$

Solution

Let $x$ be the number of points scored by the Cougars, and $y$ be the number of points scored by the Panthers. The problem is asking for the value of $y$. $$ (Error compiling LaTeX. Unknown error_msg)\begin{align*} x+y &= 34 \\ x-y &= 14 \\ 2x &= 48 \\ x &= 24 \$$The answer is$\boxed{\textbf{(A) } 10}$== Solution 2 ==$c$is the amount the Cougars scored and$p$is the score for Panthers. Since the Cougars won by 14 points,$c = p + 14$. Using substitution,$2p + 14 = 34$,$2p = 20$, and then$p = 10$.

p &= \boxed{\textbf{(A) }10} \\ \end{align*}$ (Error compiling LaTeX. Unknown error_msg)$
