Systems of Linear Equations

1. Find the solution of the equations y = 3x + 8 and 2x + y = -7.

  x = -3, y = -1
  x = 3, y = 1
  x = 3, y = -1

2. Find the solution of the equations y = 2x + 7 and 4x - y = -6

  x = 1/2, y = -6
  x = 2, y = 8
  x = 1/2, y = 8

3. Find the solution of y = 4x + 4 and y = x - 5.

  x = -3, y = -8
  x = 3, y = 8
  x = -3, y = 8
