Answer:

  (x, y) = (1, 2)

Step-by-step explanation:

You can solve this by subtracting the first equation from the second.

  (y) - (y) = (4x -2) -(-3x +5)

  0 = 7x -7 . . . . . .simplify

  0 = x -1 . . . . . . . divide by 7

  1 = x . . . . . . . . . .add 1

Use the first equation to find y:

  y = -3(1) +5

  y = 2

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