  1. 1. Solve by elimination:
    {x+2y=53x−y=8\begin{cases} x + 2y = 5 \\ 3x - y = 8 \end{cases}
  2. 2. Solve by elimination:
    {2x+y=7x+3y=11\begin{cases} 2x + y = 7 \\ x + 3y = 11 \end{cases}
  3. 3. Solve by elimination:
    {3x+2y=1x−y=−3\begin{cases} 3x + 2y = 1 \\ x - y = -3 \end{cases}
  4. 4. Solve by elimination:
    {4x+3y=102x−y=0\begin{cases} 4x + 3y = 10 \\ 2x - y = 0 \end{cases}
  5. 5. Solve by elimination:
    {x−4y=−52x+y=8\begin{cases} x - 4y = -5 \\ 2x + y = 8 \end{cases}
  6. 6. Solve by elimination:
    {5x+2y=3x+y=0\begin{cases} 5x + 2y = 3 \\ x + y = 0 \end{cases}
  7. 7. Solve by elimination:
    {3x−2y=11x+4y=−1\begin{cases} 3x - 2y = 11 \\ x + 4y = -1 \end{cases}
