Question

152x-378y=-74 and -378x+152y=-604 what is x+y:x-y=?

Answer 1

like a first step try factorizing out what is posibile

152x -378y = -74

2*76x -2*189y = -2*37

2(76x-189y) = -2*37 divide both sides by 2

76x -189y = -37

with second equation make the same

-378x +152y =-604
-2*189x +2*76y = -2*302 divide both sides by 2

-189x +76y = -302

and now there are

76x -189y =-37
-189x +76y = -302

@jdvaral please rewrite the question ! this is (x+y)/(x-y) = ?
