Question

Resolver el siguente problema:
10(t-9)-9(5-6t)=2(4t-1)+5+10t

Answer 1

☆Resolución:

10(t-9)-9(5-6t)=2(4t-1)+5+10t --->
10t - 90 - 45 + 54t = 8t - 2 + 5 + 10t --->
10t + 54t - 8t - 10t = - 2 + 5 + 45 + 90 --->
46t = 138 ---> 46t/46 = 138/46 ---> [ t = 3 ]

☆Comprobación:

10((3)-9)-9(5-6(3)) = 2(4(3)-1)+5+10(3) --->
10(-6)-9(5-18) = 2(12-1)+5+10(3) --->
10(-6)-9(-13) = 2(11)+5+10(3) --->
- 60 + 117 = 22 + 5 + 30 ---> [57 = 57]✔

☆Respuesta:

▪[ t = 3 ]
