Question

Daca a+c = -7, b+d= -35 , calculati (a+b+c)+d.
Multumesc anticipat.

Answer 1

a + c = - 7
b + d = - 35
(a + b + c ) + d = - 7 + - 35 = - 42 deoarece avem acelasi semn,deci se poate face adunarea

Answer 2

$a+c = -7 \\ b+d= -35 \\ \\ (a+b+c)+d = a+b+c+d = (a+c)+ (b+d) = -7-35=\boxed{-42}$
