Question

Determine the solution, if it exists, for each system of linear equations. Verify your solution on the coordinate plane.

Answer 1

Answer:

  (x, y) = (2, 1)

Step-by-step explanation:

Adding the two equations gives ...

  2y = 2

  y = 1 . . . . . divide by 2

Subtracting the second equation from the first gives ...

  0 = 6x -12

  0 = x -2 . . . . divide by 6

  2 = x

The solution is (x, y) = (2, 1).
