pooja195 (pooja195):

Opposites cancel -2( x + y = 4) Distribute the -2

OpenStudy (anonymous):

i dont know how to do that

pooja195 (pooja195):

-2 * x =? -2 * y =? -2 * 4 =?

OpenStudy (anonymous):

-2x, -2y, -24

pooja195 (pooja195):

-24?

OpenStudy (anonymous):

i dont know that one

pooja195 (pooja195):

2x + 2y =8 -2x -2y=-8

pooja195 (pooja195):

2-2= ?

OpenStudy (anonymous):

0

pooja195 (pooja195):

x's cancel out 2-2= ?

pooja195 (pooja195):

i said zero

pooja195 (pooja195):

great now 8-8= ?

OpenStudy (anonymous):

zero

pooja195 (pooja195):

good so everything cancels out therefore when we have 0=0 it is infinte solution its not always 0 it can me #=# but it has to be the same number for it to be infinte
