Question

Alguien que me pueda ayudar a resolver esto-2(y-1)+{-4(y-1)-5[y-2(4-y)+3y]-(y+1)}=2y-(-5-y)

Answer 1

Respuesta:

y = 1

Explicación:

-2(y-1)+{-4(y-1)-5[y-2(4-y)+3y]-(y+1)} = 2y-(-5-y)

-2(y-1)+{-4(y-1)-5[y-2(4-y)+3y]-(y+1)} = 2y + 5 + y

-2y + 2 +{-4y + 4 -5[y-8+2y+3y]-y-1} = 3y + 5

-2y + 2 +{-4y + 4 -5[6y-8]-y-1} = 3y + 5

-2y + 2 +{-4y + 4 -30y+40-y-1} = 3y + 5

-2y + 2 +{-35y+43} = 3y + 5

-2y + 2 - 35y + 43 = 3y + 5

-37y + 45 = 3y + 5

-37y - 3y = 5 - 45

-40y = -40

y=-40/-40

y = 1

Answer 2

Explicación:

-2(y-1)+{-4(y-1)-5[y-2(4-y)+3y]-(y+1)}=2y-(-5-y)

-2y+2+{-4y+4-5[y-8+2y+3y]-y-1}=2y+5+y

-2y+2+{-4y+4-5y+40-25y-y-1}=3y+5

-2y+2-35y+43=3y+5

40=40y

y=1
