solve the system of equations by graphing. Then classify the system as consistent or inconsistent and the equations as dependent or independent.
x+y=14
x-y=2

What is the solution of the system of equations?

  • algebra -

    I can not very well graph them here and see where they hit, but I can add them
    2 x + y - y = 14 + 2
    2 x = 16
    x = 8
    then
    8 + y = 14
    y = 6
    so your lines should intersect at (8,6)

  • algebra -

    re the two functions parallel, perpendicular, the same equation or none of these choices?

    4x+4y=8

    5x+5y=15
