Question

me podeis dar las soluciones porfavor? :

1) 4·(2-5)+2·(5-7)-3·(6-8)=
2) 2·(3-9)-6·(5-6-4·(8-9)=

Answer 1

$4*(2-5)+2*(5-7)-3*(6-8)= \\ \\ 4*(-3)+2*(-2)-3*(-2)= \\ \\ -12-4+6= \\ \\ -12+2= \\ \\ \boxed{-10} \\ \\ \\ \\ 2*(3-9)-6*(5-6-4)*(8-9)= \\ \\ 2*(-6)-6*(-5)*(-1)= \\ \\ -12+30*(-1)= \\ \\ -12-30= \\ \\ \boxed{-42}$
