rezolvati urgent va rog dau si coroana​

Answer 1

Salutare!

a)

a = 2

b = 4

c = 6

$\bf a-(b-c) = 2-(4-6)=2-(-2) = 2+2 =\boxed{\bf 4}$

b)

a = -12

b = -14

c = -8

$\bf a-(b-c)= -12-[-14-(-8)]=-12-(-14+8) =-12-(-6)=-12+6=$

$\bf a-(b-c)= \boxed{\bf -6}$

c)

a = -6

b = -3

c = -15

$\bf a-(b-c)= -6-[-3-(-15)]=-6-(-3+15) =-6-(+12)=-6-12=$

$\bf a-(b-c)= \boxed{\bf -18}$
