Sagot :

Answer:

  (x, y) = (1, 8)

Step-by-step explanation:

Maybe your equations are ...

  • y = 2x +6
  • y = -3x +11

Equating the values of y, we have ...

  2x +6 = -3x +11

  5x = 5 . . . . . . . . . . add 3x-6

  x = 1 . . . . . . . . . . . divide by 5

  y = 2(1) +6 = 8

The solution is (x, y) = (1, 8).
