Use linear combination <br><br> 4x-9y=1<br> -2x+3y=-1
kirill [66]

Answer:

  (x, y) = (1, 1/3)

Step-by-step explanation:

The x-coefficient in the first equation is -2 times that in the second equation, so adding twice the second equation to the first will eliminate x:

  (4x -9y) +2(-2x +3y) = (1) +2(-1)

  -3y = -1 . . . . simplify

  y = 1/3 . . . . . divide by -3

The y-coefficient in the first equation is -3 times the y-coefficient in the second equation, so adding 3 times the second equation to the first will eliminate y:

  (4x -9y) +3(-2x +3y) = (1) +3(-1)

  -2x = -2 . . . . . . simplify

  x = 1 . . . . . . . . . divide by -3

The solution is (x, y) = (1, 1/3).
