Question

se a= -2x+3y-1 b= 2x+3y+2 c=2x-y+3 calcule o valor de a-b-c

Answer 1

a - b - c =
(-2x+3y-1) - (2x+3y+2) - (2x-y+3) =
-2x + 3y -1 - 2x - 3y - 2 - 2x + y - 3 =
-6x + y - 6

Answer 2

a= -2x+3y-1

b= 2x+3y+2

c=2x-y+3

a-b-c

(-2x+3y-1) - (2x+3y+2) - (2x-y+3)

-2x +3y -1 -2x -3y -2 -2x + y -3

-6x +y -6
