Hi! How to determine other linear systems that have the same solution as this system:
2x+5y=8
x-3y=-7
many thanks.

  • Math -

    change the equation 2x+5y=8 into the form of y=ax+b and then substitute for the value of X by ( 0 , 1 , 2 , 3 ) 3 points are enought and line them on a graph..

    Note : the second equation has the same way!
