7(y-4)²-3(y+5)²=4(y+1)(y-1)-2

(y+1)³+3=(y-2)³+9y²+2y+5

Answer 1

Respuesta:

-2[x-(5-4x)]+4=3x

−2 x − 5 − 4x + 4 = 3x

−2 x(x- (− 5 − 4x)) + 4

= −2 (5x − 5) + 4

= −10x + 10 + 4

Sumar: 10 + 4 = 14

−10x + 14  = 3x

Restar 14 de ambos lados

−10x + 14 − 14 = 3x − 14

−10x = 3x − 14

Restar 3x de ambos lados

−10x − 3x = 3x − 14 − 3x

−13x = −14

x= −14 /−13

x = 14/13

9x-(5x+1)-[2+8x-(7x-5)]+9x=0

9x − 5x + 1 − 2 + 8x − 7x − 5 + 9x = 0

9x + 9x − (5x + 1) −( 8x −( 7x−5) + 2) = 0

18x − (5x + 1 )−( 8x − (7x − 5) + 2) = 0

18x-(5x)+1)-(x+7)

18x - 5x - 1 - x - 7

12x − 8 = 0

Sumar 8 a ambos lados

12x − 8 + 8 = 0 + 8

12x = 8

x= 8 /12

x =2/ 3

(x-3)²=(x+2)(x-5)

7(y-4)²-3(y+5)²=4(y+1)(y-1)-2

(y+1)³+3=(y-2)³+9y²+2y+5
