Question

cual es el valor de 3(a+b)+2(c+d) si a =2; b= 5;c=-3; d = 7​

Answer 1

Explicación paso a paso:

\begin{gathered}3(a-b)+2(c-d) = \\ \\ 3((2)-(5))+2((-3)-(-1))= \\ \\ 3(2-5)+2(-3+1)= \\ \\ 3(-3)+2(-2)= \\ \\ - 9 - 4= \boxed{-13} \end{gathered}

3(a−b)+2(c−d)=

3((2)−(5))+2((−3)−(−1))=

3(2−5)+2(−3+1)=

3(−3)+2(−2)=

−9−4=

−13
