Es para hoy u-u

Answer 1

• Ecuaciones ....

ℙ →

$4x – (2x – 1) + x = 2x – (2 + x) - x$

ℝ →

$4x – (2x – 1) + x = 2x – (2 + x) - x$

$4x - 2x + 1 + x = 2x - (2 + x) - x$

$4x - 2x + 1 + x = 2x - 2 - x - x$

$3x + 1 = 2x - 2 - x - x$

$3x + 1 = 0 - 2$

$3x + 1 = - 1 \\ 3x = - 2 - 1 \\ 3x = - 3 \\ x = - 1$
