Explicación paso a paso:
A = (-8) (+2) - 3
A = -16 - 3
A = -19
B = (+4) (-2) + 4
B = -8 + 4
B = -4
C = (50) ÷ (-2) - 6
C = -25 - 6
C = -31
Halla:
a.
A + B + C
(-19) + (-4) + (-31)
-19 - 4 - 31
-23 - 31
-54
b.
A × B + C
(-19) × (-4) + (-31)
+76 - 31
+45
c.
2B - 3A
2(-4) - 3(-19)
-8 + 57
+49
d.
2A × B
2(-19) × (-4)
-57 × (-4)
