b. (–18) ÷ (+6) + (–9) + 24 ÷ (–3) + 7x (–2) + 4 x (–3)
son separados cada uno

Answer 1

Respuesta:

= -48x - 55

Explicación paso a paso:

[4 + 12 (-2) + 4 x (-3) 4 + 15 (-3) - 4 (-2) + 2]

=12(-2) +15(-3) -4(-2) +4x(-3) .  4+4+2

=12(-2) +15(-3) -4(-2) +4r(-3)  .  4+6

= 8(—2) + 15(—3) +4x(—3)  .  4 + 6

8(-2) = -16

15(-3) = -45

4x(-3) .  4= -48x

= -16-45-48x+6

= -48x-16-45+6

= -48x - 55
