Question

simplificación de expresiones algebraicas

Answer 1

a) (-18x+8y)+(3x-2y)= -15x+6y
b) -5b+3c
c) 0'4x-3'7+0'6x-x+0'5+2'6y= 1'4x-3'2+2y
d)-3x-2x-y-6x-6y-x+4y= -12x-3y
e) 1/3(x/4 - 2x/4 + 4z/4)-x-y-z = -1x/12 + 2y/12 - 4z/12 -x-y-z = -2x+y-5z
f) 2mn^3 -8m+6m^2+ m^2n + 4m^2 -n^2 -3m = 2mn^3 - 11m +10m^2 + m^2n -n^2
g) (-1/5)·(6/3x-10/2x) = (-1/5)·(12/6 - 30/6) =(-1/5)·(-18/6) = 18/30 = 3/5
