Question

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

Answer 1

Respuesta:

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

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

12x = 23

x = 1.916

Explicación paso a paso:

Answer 2

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

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

4x - 3 = -8x - 6

4x + 8x = -6 + 3

12x = -3

x = -3/12 ... simplificando (ambos tienen factor comun 3)

x = -1/4
