Question

1. Daca a+b = -35 , c= -35 , calculati c+(a+b). 2. Daca a= +25 , b+c=-38 , calculati a+b+c. 3. Daca a+b= -96 , c+d= + 97 , calculati a+b+c+d Va rog!! urgent . CORONITAA

Answer 1

$1).a+b=-35 \\ c=-35 \\ c+(a+b)=-35+(-35)=-70 \\ 2).a=25 \\ b+c=-38 \\ a+b+c=25+(-38)=-13 \\ 3).a+b=-96 \\ c+d=97 \\ a+b+c+d=-96+97=1$

Answer 2

$Rezolvare:1)a+b=-35 \\ c=-35 \\ c+(a+b)=-35+(-35)= \\ =\boxed{-70} \\ 2)a=+25 \\ b+c=-38 \\ a+b+c=25-38= \\ =\boxed{-13} \\ 3)a+b=-96 \\ c+d=97 \\ a+b+c+d=-96+97= \\ =\boxed{1}$
