Simple systems

  1. 1. Is the ordered pair a solution of the system:
    {x+y=5x−y=1(3,2)\begin{cases} x + y = 5 \\ x - y = 1 \end{cases}\quad (3, 2)
  2. 2. Is the ordered pair a solution of the system:
    {x+y=7x−y=3(5,2)\begin{cases} x + y = 7 \\ x - y = 3 \end{cases}\quad (5, 2)
  3. 3. Is the ordered pair a solution of the system:
    {x+y=6x−y=2(3,3)\begin{cases} x + y = 6 \\ x - y = 2 \end{cases}\quad (3, 3)
  4. 4. Is the ordered pair a solution of the system:
    {y=2xx+y=9(3,6)\begin{cases} y = 2x \\ x + y = 9 \end{cases}\quad (3, 6)
  5. 5. Is the ordered pair a solution of the system:
    {y=x+1x+y=7(3,4)\begin{cases} y = x + 1 \\ x + y = 7 \end{cases}\quad (3, 4)
  6. 6. Is the ordered pair a solution of the system:
    {y=3xx+y=8(2,5)\begin{cases} y = 3x \\ x + y = 8 \end{cases}\quad (2, 5)
  7. 7. Is the ordered pair a solution of the system:
