posted by .

write two other equations that have the same solution as this system od equations.
3x-4y=-14
-x+3y=18

I found the solution to the system it is (6,8) there after how do i go about it?

  • Math - system of equations -

    Just make up any old left-side of an equation.

    e.g. 5x - 2y = ??
    now plug in your values to get
    30 - 16 = 14

    so one equation is 5x - 2y = 14

    as you can see there would be an infinite number of equations you could form

  • Math - system of equations using elimination -

    x-4y=-2
    5x-y=-3

  • Math - system of equations -

    2x+y+z=0,x+y+2z=0,5x+3y+3z=2

  • Math - system of equations -

    x=-2,y=6,z=-2
