Question

X +3(x-1) = 6-4 (2x +3)​

Answer 1

Respuesta:

x = -1/4

Explicación paso a paso:

x + 3(x-1) = 6 - 4(2x+3)

x + 3*x + 3*-1 = 6  -4*2x -4*3

x + 3x - 3 = 6 - 8x - 12

x + 3x + 8x = 6 - 12 + 3

12x = -3

x = -3/12

x = -1/4

Comprobación:

-1/4 + 3(-1/4 - 1) = 6 - 4(2*-1/4 + 3)

-1/4 + 3(-1/4 - 4/4) = 6 - 4(-2/4 + 12/4)

-1/4 + 3(-5/4) = 6 - 4*10/4

-1/4 - 15/4 = 24/4 - 40/4

-1 -15 = 24 - 40 = -16
