Explicación paso a paso:
x = - 2
y = - 4
z = - 1
3x + xy + y^3 - 7z
= 3 ( - 2 ) + ( - 2 ) ( - 4 ) + ( - 4 )^3 - 7 ( - 1 )
= - 6 + 8 - 64 + 7
= 2 - 57
= - 55

Explicación paso a paso:
3x + xy + y^3 - 7z + 9
= 3 ( - 2 ) + ( - 2 ) ( - 4 ) + ( - 4 )^3 - 7 ( - 1 ) + 9
= - 6 + 8 - 64 + 7 + 9
= 2 - 57 + 9
= - 55 + 9
