-2(3x – 3) = -3

5(x+2) =3(x+2) + 1

Answer 1

¡Hola!

Explicación paso a paso:

1.

$4(2 + 3x) = 5 \\ 8 + 12x = 5 \\ 12x = 5 - 8 \\ 12x = - 3 \\ x = - \frac{3}{12} \\ x = - \frac{1}{4}$

2.

$- 2( 3x - 3) = - 3 \\ - 6x + 6 = - 3 \\ - 6x = - 3 - 6 \\ - 6x = - 9 \\ x = \frac{ - 6}{ - 9} \\ x = \frac{2}{3}$

3.

$5(x + 2) = 3(x + 2) + 1 \\ 5x + 10 = 3x + 6 + 1 \\ 5x - 3x = 6 + 1 - 10 \\ 2x = - 3 \\ x = - \frac{3}{2}$
