2+ [ 4+ (-3 +(-4) ]

{-2 x[3 + (-2) (+ 5)]}

{8x [3 + (-12)÷(+2 )]}

Answer 1

Respuesta:

Explicación paso a paso:

3 + [ 2x (-7 +3) ]=

=3+−8x

=−8x+3

2+ [ 4+ (-3 +(-4) ]

=2+4+−7

=2+−3

=−1

{-2 x[3 + (-2) (+ 5)]}

=(−2x)(3+(−2)(5))

=(−2x)(3)+(−2x)((−2)(5))

=−6x+20x

=14x

{8x [3 + (-12)÷(+2 )]}

=(8x)(3+ −12 /2 )

=(8x)(3)+(8x)( −12 /2 )

=24x−48x

=−24x
