Question

-{3x+8-[-15+6x-(-(3x+2)-(5x+4))]-29=-5

Answer 1

RESOLVIENDO:

-{3X + 8 -[-15 + 6X -(-(3X + 2) - (5X + 4))]} - 29 = -5
-{3X + 8 -[-15 + 6X -(-3X - 2) - 5X - 4]} - 29 = -5
-{3X + 8 -[-15 + 6X + 3X + 2 - 5X - 4]} - 29 = -5
-{3X + 8 -[ 4X - 17]} - 29 = -5
-{3X + 8 - 4X + 17} - 29 = -5
-{-X + 25} - 29 = -5
X -25 -29 = -5
X - 54 = -5
X = 54 - 5
X = 49 ===> Respuesta

MUCHA SUERTE...!!!
